After a dramatic change of government in West Bengal, the next big electoral battle is for Kolkata itself. The Kolkata Municipal Corporation (KMC) election 2026 will be the first civic poll in the city since the BJP won the state Assembly in May 2026, ending the Trinamool Congress’s 15-year rule. The number of wards has been increased from 144 to 209, the corporation is currently run by an administrator, and polls are expected in late November or the first week of December 2026.
For the BJP, winning Kolkata, which has been a TMC fortress for over a decade, would complete its takeover of Bengal. For Mamata Banerjee’s party, the KMC is a test of survival. In this Election Guru explainer we cover the expected dates, the ward expansion, why the old board was dissolved, the parties in the fray, the 2021 result and the other six civic bodies going to polls.

When Will the Kolkata Municipal Election Be Held?
The West Bengal State Election Commission has not yet announced an official schedule. Different reports give slightly different timelines:
| Source | What It Said |
|---|---|
| Chief Minister Suvendu Adhikari (June 2026, PTI) | KMC elections will be held by the first week of December |
| India TV, citing sources (24 Sept 2026) | Polls in the last week of November, around 27-28 November; results in early December |
| Wikipedia (current) | Tentatively within 7 December 2026 |
With the Model Code of Conduct for civic polls usually announced about three to four weeks before voting, an announcement is expected soon.
Why Was the KMC Board Dissolved?
After the TMC’s defeat in the 2026 Assembly election, Mayor Firhad Hakim resigned on 3 June 2026. Many TMC councillors also resigned, and the corporation was eventually dissolved. On 9 June 2026, Smita Pandey was appointed administrator of the KMC, and the city has been run without an elected board since then.
Wards Increased from 144 to 209
In August 2026, the West Bengal Legislative Assembly passed the Kolkata Municipal Corporation (Amendment) Bill, 2026, which increased the number of wards from 144 to 209. That means 65 new wards, a fresh delimitation of ward boundaries and new reservation rosters. Supporters say the change reflects the city’s growth and makes wards more manageable. The opposition has questioned whether the new boundaries were drawn to benefit the ruling party, a charge often made whenever wards are redrawn before civic polls.
| Item | Old KMC | New KMC |
|---|---|---|
| Wards | 144 | 209 |
| Majority mark | 73 | 105 |
| Governing party at election time | TMC (2021) | BJP (2026) |
2021 KMC Election Result
In the last KMC election in December 2021, the TMC won a crushing victory, and Firhad Hakim became mayor for a second term.
| Party | Seats Won (of 144) |
|---|---|
| TMC | 134 |
| BJP | 3 |
| Left Front | 2 |
| Congress | 2 |
| Independents | 3 |
The BJP polled about 9% of the vote in Kolkata in 2021. Five years later, it is the ruling party in the state, which makes the 2026 KMC election one of the most unpredictable civic contests in the country.
Bengal Assembly Election 2026: The Background
In the 2026 West Bengal Assembly election, the BJP won 208 of 294 seats, ending Mamata Banerjee’s 15-year rule, and Suvendu Adhikari became Chief Minister. Since then, the TMC has faced defections and splits, and many of its councillors and leaders have left the party. Mamata Banerjee has alleged that the BJP won through a conspiracy with the Election Commission, demanded a repoll in Bengal, and sought the arrest of CEC Gyanesh Kumar over the Special Intensive Revision (SIR) of voter lists.

Key Issues in the Kolkata Civic Election

- Garbage management and the Dhapa landfill
- Water supply in added areas of the city
- Roads, traffic and parking
- Property tax and civic service charges
- Voter list deletions under the SIR exercise
What to Watch
| Question | Why It Matters |
|---|---|
| Can BJP win Kolkata? | Kolkata has never had a BJP mayor; a win would be historic |
| How much of TMC’s vote survives? | A test of Mamata Banerjee’s hold after the Assembly defeat |
| Left-Congress revival? | Urban Kolkata was once a Left stronghold |
| Effect of 65 new wards | New boundaries could reshape local equations |
| Voter roll changes | SIR deletions are a major political issue |
History of the Kolkata Municipal Corporation
The Kolkata Municipal Corporation, formerly the Calcutta Corporation, is one of India’s oldest civic bodies. Its mayors have included some of the biggest names in the freedom movement.
| Period | Mayor / Ruling Group | Note |
|---|---|---|
| 1924 | Chittaranjan Das | First mayor; Subhas Chandra Bose was chief executive officer |
| 1930 | Subhas Chandra Bose | Served as mayor |
| 1985 – 2000 | Left Front | Left controlled the corporation |
| 2000 – 2005 | Subrata Mukherjee (TMC) | First TMC mayor |
| 2005 – 2010 | Bikash Ranjan Bhattacharya (Left Front) | Left returned |
| 2010 – 2018 | Sovan Chatterjee (TMC) | TMC took control |
| 2018 – 2026 | Firhad Hakim (TMC) | Resigned on 3 June 2026 |
KMC Election Results Over the Years
| Year | Total Wards | Winner | Seats Won |
|---|---|---|---|
| 2010 | 141 | TMC | 95 |
| 2015 | 144 | TMC | 114 |
| 2021 | 144 | TMC | 134 |
| 2026 | 209 | ? | To be decided |
The TMC’s tally rose with each election, peaking at 134 in 2021. The BJP’s best KMC result so far was 7 wards in 2015. For the BJP to win a majority of 105 in 2026, it will need the kind of swing it achieved in the Assembly election.
How the Kolkata Mayor Is Chosen
In the KMC, voters elect councillors ward by ward. The councillors of the majority party or alliance then elect the mayor, who leads a Mayor-in-Council, a cabinet-style executive of senior councillors. A separate chairperson presides over the house of councillors. With 209 wards, the party that wins at least 105 will choose the mayor.
How to Check Your Name in the KMC Voter List
- Visit the West Bengal State Election Commission website (wbsec.gov.in) once the final civic roll is published
- Check the KMC ward-wise draft roll published in October 2026
- Note that ward numbers have changed after the expansion to 209 wards, so check your new ward
- Contact the ward office or borough office of the KMC for corrections
Bengal’s Changed Political Map
| Election | Winner | Key Figure |
|---|---|---|
| 2011 Assembly | TMC | Mamata Banerjee ends 34 years of Left rule |
| 2016 Assembly | TMC | Mamata re-elected |
| 2021 Assembly | TMC | Third term despite BJP push |
| 2021 KMC | TMC | 134 of 144 wards |
| 2026 Assembly | BJP | 208 of 294 seats; Suvendu Adhikari CM |
| 2026 KMC | Pending | First civic test of BJP government |
Why Kolkata Matters So Much
Kolkata is not just Bengal’s capital. It is the state’s economic centre, its media hub and the place where political narratives are made. The TMC built its rise in the city, from Mamata Banerjee’s years as a Congress youth leader to its first KMC win in 2000. Losing Kolkata would mean the TMC loses its last big power centre after the Assembly defeat. For the BJP, a KMC win would show that its support is not just in rural and border districts but also among urban, middle-class and Bengali bhadralok voters, who have traditionally been wary of it.
Possible Outcomes
| Scenario | What It Would Mean |
|---|---|
| BJP wins majority (105+) | Complete takeover of Bengal; first BJP mayor of Kolkata |
| TMC holds Kolkata | Mamata Banerjee’s party survives as main opposition with a strong city base |
| Hung corporation | Left-Congress or independents could become kingmakers |
| Left revival | A comeback in a city the Left once ruled for 15 years |
Whatever the result, the KMC election will be the first direct test of Chief Minister Suvendu Adhikari’s government in the capital and of the opposition’s ability to regroup after the Assembly defeat.
Timeline of Key Events in 2026
| Date | Event |
|---|---|
| May 2026 | BJP wins West Bengal Assembly election |
| 3 June 2026 | Mayor Firhad Hakim resigns |
| 9 June 2026 | Smita Pandey appointed KMC administrator |
| August 2026 | KMC (Amendment) Bill passed; wards raised to 209 |

Left and Congress: Can They Make a Comeback?
The Left Front ruled West Bengal for 34 years until 2011 and controlled the Kolkata corporation for most of the 1980s and 1990s. Since then its vote has collapsed, and in the 2021 KMC election it won only two wards. The Congress has also been reduced to a marginal player in the city. With the TMC weakened after its Assembly defeat, both parties hope that some anti-BJP voters who no longer trust the TMC will return to them. CPI(M) state secretary Mohammed Salim and Congress state president Subhankar Sarkar are expected to decide whether to fight together, as they did in some earlier elections.
Role of the State Election Commission
Municipal elections in West Bengal are conducted by the West Bengal State Election Commission, not the Election Commission of India. The State Election Commission notifies the schedule, prepares the civic voter roll based on the Assembly roll, oversees ward reservation and announces results. In past civic polls, opposition parties have often alleged violence and booth capturing, and courts have been asked to order central forces. Whether central forces are deployed in 2026, now that the BJP is in power in the state, will be one of the first questions once the schedule is announced.
| Task | Done By |
|---|---|
| Ward delimitation and reservation | State government / State Election Commission |
| Civic voter list | State Election Commission (based on Assembly rolls) |
| Poll schedule and Model Code | State Election Commission |
| Election of mayor | Newly elected councillors |
Election Guru Analysis
The KMC election 2026 is the BJP’s chance to show that its Assembly victory has deep roots in Bengal’s capital, and the TMC’s chance to prove it can still win where it was strongest. With 209 newly drawn wards, an administrator in charge and the opposition split, the result is hard to predict. Election Guru will bring you the full schedule as soon as the State Election Commission announces it, followed by ward-wise results.
