NEW DELHI: An Indian court renewed detention on Monday for key opposition leader Arvind Kejriwal until April 15 in a graft case, his lawyers said, less than three weeks before voting begins in general elections.

In a move that sparked protests last month, India’s financial crime-fighting agency arrested Kejriwal, the chief minister of Delhi, over graft accusations related to the city’s liquor policy and he was remanded to custody until April 1.

Opposition parties say the arrest, along with government action against other opposition groups and their leaders, shows the government is denying them a level playing field in the elections, charges it denies. Kejriwal’s Aam Aadmi Party (AAP) says he has been falsely arrested in a fabricated case, but Prime Minister Narendra Modi’s Bharatiya Janata Party (BJP) denies political interference.

Lawyers for the agency, the Enforcement Directorate, said on Monday that Kejriwal had been non-cooperative and gave evasive replies, asking the court to hold him in custody for 15 days longer, the website Live Law said.
