Several Left leaders, including Kerala Chief Minister Pinarayi Vijayan and senior CPI(M) leader Brinda Karat, were detained in New Delhi on Wednesday ahead of a proposed protest at Jantar Mantar, according to officials.

The protest was planned against Chief Election Commissioner Gyanesh Kumar, though no further details on the reason for the demonstration were immediately available from the input.

It was not immediately clear how many people were detained or whether the protest went ahead. The situation remained under observation.
