Left without power nationwide for the first time since 1977

In central Kerala, where the Christian community shapes electoral outcomes, the UDF won all 28 seats across Ernakulam, Kottayam and Idukki, doubling its 2021 tally of 14. The shift is attributed in part to concerns over the Foreign Contributions Regulation Act amendment and to the NDA fielding candidates from the Twenty-20 party in seats where the organisation is considered weak.

In north Kerala, the UDF benefited from remarks by Vellappally Natesan, chief of the Ezhava community, who publicly backed Vijayan and the LDF but alleged discrimination against Ezhavas in Muslim-majority districts such as Malappuram; the CPI(M)'s perceived failure to rebut those remarks is seen as consolidating Muslim votes against the LDF.

The campaign attacked price rise, unemployment, public debt, and allegations that CPI(M) leaders and Devaswom officials were involved in the theft of gold assets from the Sabarimala temple, a case being investigated by a special investigation team of the Kerala Police.

The UDF won 102 of 140 seats in Kerala's assembly, while the CPI(M)-led LDF won 35 seats; 13 sitting ministers lost their constituencies. Within the coalition, Congress won 63 of 92 seats it contested; the Indian Union Muslim League won 22 of 27; the Kerala Congress faction led by PJ Joseph won seven of eight; the BJP-led NDA won three seats.

In December 2025, the UDF won local body polls with 38.81% of votes against the LDF's 33.45%, taking a majority of grama panchayats, block panchayats, municipalities and municipal corporations.

The Left Democratic Front led by CPI(M) won 99 seats in the 2021 Kerala Assembly.

The Congress-led United Democratic Front won 111 seats in the 1977 Kerala Assembly after the Emergency, marking its largest tally in the state's history.
