West Bengal 2026 Elections: Parties Whose Candidates Lost Deposits In The 2021 Assembly Polls

The 2021 West Bengal deposit forfeiture data from the Election Commission highlights the true level of party competition beyond seat tallies. It shows TMC maintained zero deposits forfeited across 290 seats, while BJP faced selective losses. The data also exposes weaknesses among CPI(M), Congress and other smaller parties, informing future electoral strategies and potential 2026 dynamics.

The 2021 West Bengal Assembly election is mostly remembered for TMC’s big win and BJP’s rise. Yet another layer of data tells a quieter story. Deposit forfeiture figures show where parties were truly in the contest, and where they were barely visible despite appearing on the ballot.

Under Indian election rules, candidates must get at least one-sixth, or 16.67 per cent, of valid votes. Otherwise, they forfeit their security deposit. This simple threshold turns into a helpful indicator of real competitiveness, beyond headline seat counts and broad state-wide vote shares.

2021 West Bengal election deposit forfeiture as a map of real competition

The Election Commission of India’s “Performance of Political Parties” report for West Bengal 2021 offers detailed numbers. It lists, for every recognised party, seats contested, victories, deposit forfeitures, votes polled and total vote share. When read together, these figures show how sharply uneven the electoral field actually was.

Across parties, the deposit picture is striking. TMC did not lose a single deposit in 2021. BJP, while becoming the main opposition, still saw 11 candidates fall short of the cut-off. For Congress, CPI(M) and other Left partners, the pattern was far more severe, with large-scale losses.

TMC’s 2021 West Bengal election deposit forfeiture record shows broad strength

Among all parties, TMC’s numbers stand out most clearly. The party contested 290 seats. Out of these, TMC won 215. Yet in none of the 290 constituencies did a TMC candidate lose the deposit, which means every candidate secured more than 16.67 per cent of valid votes.

This clean record suggests TMC’s base was both wide and deep in 2021. Even where TMC failed to win the seat, the party still remained a serious contender. On the deposit measure, TMC was competitive almost everywhere, highlighting an extensive organisational and vote presence across West Bengal.

BJP’s 2021 West Bengal election deposit forfeiture numbers show uneven gains

The BJP entered the 2021 West Bengal Assembly election aiming to challenge TMC across the state. BJP fielded candidates in 293 seats, won 77 of them, and secured a vote share of 37.97 per cent. On the surface, this confirmed BJP as the principal opposition force.

However, deposit data underlines the limits within that advance. BJP candidates forfeited deposits in 11 constituencies. These seats were places where BJP support stayed below 16.67 per cent. The pattern signals that, even at this high point, BJP still lacked traction in several pockets of West Bengal.

How the 2021 West Bengal election deposit forfeiture data looks in numbers

The Election Commission’s report allows a clear party-wise comparison for 2021, excluding independents. The following table lists seats contested, seats won and deposits forfeited by key parties, along with an at-a-glance summary of deposit losses that signals their level of competitiveness.

Left and Congress in the 2021 West Bengal election deposit forfeiture data

The Left-Congress alliance, organised as the Sanjukta Morcha, struggled badly on deposit retention. CPI(M) contested 139 seats and failed to win any. In 120 of those constituencies, CPI(M) candidates lost their deposits, which indicates very low vote shares in most areas they contested.

Congress recorded a similar pattern of weakness. Out of 92 seats contested, Congress did not win any, and 79 candidates forfeited deposits. Smaller Left partners also faced steep losses. CPI lost deposits in all 10 seats. AIFB candidates forfeited in 20 of 21 constituencies, while RSP lost deposits in 10 of 11.

What 2021 West Bengal election deposit forfeiture says about the Left-Congress bloc

The deposit figures show that defeat for the Left and Congress went beyond seat tallies. In many constituencies, these parties did not even reach the basic 16.67 per cent mark. CPI(M) failed to retain deposits in the overwhelming majority of seats. Congress lost deposits in most of its contests.

For several Left allies, the deposit washout was near total. On this metric, sections of the old Left-Congress space had shrunk to pockets where they barely registered. The numbers therefore capture how strongly the state’s politics had shifted towards a TMC versus BJP structure by 2021.

ISF’s role in the 2021 West Bengal election deposit forfeiture picture

Within the broader anti-TMC, anti-BJP space, ISF formed a small but distinct presence. In the Election Commission report, ISF appears under the name or code RSSCMJP. The party contested 32 seats, won 1, and recorded a total vote share of 1.35 per cent across West Bengal.

ISF candidates forfeited deposits in 23 constituencies, so the party also faced many weak zones. Yet, compared with some alliance partners, ISF managed relatively stronger performances in select areas. Most notably, Bhangar was won by Nawsad Siddique, making ISF the only Sanjukta Morcha constituent to secure a seat.

Smaller parties in the 2021 West Bengal election deposit forfeiture data

The 2021 West Bengal Assembly election also featured many smaller national and regional parties. On the ballot, these parties appeared across numerous constituencies. But the deposit numbers showed that several had almost no meaningful vote base in the seats where they fielded candidates.

BSP contested 162 seats and lost deposits in all 162. AIMIM saw its 6 candidates forfeit deposits in each seat. CPI(ML)(L) recorded 12 out of 12 deposit losses. IUML faced 4 out of 4, JD(U) 16 out of 16, LJP 10 out of 10, and SUCI 190 out of 190.

Overall 2021 West Bengal election deposit forfeiture snapshot

A broader summary, again excluding independents, highlights which parties kept deposits intact and which did not. Among major parties, deposit losses were: TMC 0, BJP 11, CPI(M) 120, Congress 79, CPI 10, BSP 162, AIFB 20, RSP 10, and ISF or RSSCMJP 23. These numbers underline differing levels of competitiveness.

Other notable parties also present a clear picture. AIMIM saw 6 deposit losses. AJSUP contested just one seat and retained that candidate’s deposit. CPI(ML)(L) recorded 12 forfeitures. IUML had 4, JD(U) 16, LJP 10 and SUCI 190 deposit losses. For many of these, presence on paper did not translate into substantial vote shares.

Using 2021 West Bengal election deposit forfeiture data to read 2026 prospects

Looking ahead to the 2026 West Bengal Assembly election, the 2021 deposit data offers several lessons. TMC’s zero deposit losses reflect a broad, stable base across constituencies. BJP’s 11 forfeitures show that, while strong in many areas, the party still had clear weak pockets.

The deep losses for CPI(M), Congress and other Left allies reveal how firmly the state’s contest had narrowed to two main poles. ISF’s ability to win Bhangar, despite a low overall vote share, suggests that smaller parties may yet play roles in concentrated regions, especially where local networks are strong.

Why 2021 West Bengal election deposit forfeiture matters for reading party strength

Deposit-forfeiture numbers for 2021 do more than provide background statistics. They help identify areas where parties are structurally fragile and where alliances might be decisive in 2026. They also show which regions have genuine multi-party competition and which see mostly symbolic entries on ballot papers.

A party contesting widely can appear strong when listed seat by seat. Yet if many of its candidates fail to clear the 16.67 per cent threshold, its real presence is limited. In West Bengal’s 2021 election, deposit data therefore supplied a sharp view of who was actually in the fight and who was not.
