Security lockdown in central Delhi

Six Delhi metro stations were closed on Monday for "security reasons", with police saying traffic restrictions and diversions would be imposed in 20 locations as opposition parties prepared an election protest march to the supreme court. Thousands of security personnel locked down central Delhi to stop the march.

The restrictions came after a weekend of sweeping detentions:

• •Police detained thousands of protesters in Delhi over the weekend.
• •Among those detained were leaders of the Cockroach Janta party (CJP).

The march to the supreme court

The Congress party announced the march to the supreme court, where it intended to submit a memorandum to the Chief Justice demanding an end to what it calls "vote theft" and the resignation of chief election commissioner Gyanesh Kumar.

Rahul Gandhi said on X: "Youth, all opposition parties, civil society groups, all those who believe in democracy and stand by the Constitution of India, will walk with us".

Chief Justice Surya Kant declined a meeting request by email, saying the issue should be addressed through judicial proceedings, according to a Congress source.

The voter list dispute

The target of the protests is a controversial revision of voter lists that has sparked days of unrest in Delhi. Critics say the revision benefits prime minister Narendra Modi's Bharatiya Janata party (BJP).

• •The revision, which started last year, deleted over 130 million names from voter lists during a verification exercise - more than the population of Japan.
• •The deleted names included 30 million people who could not be traced, 28 million who had died and 63 million who had relocated.
• •Opposition parties allege Muslim voters and other minorities are disproportionately affected by the deletions.

The Election Commission denied favouring any party and said wrongly deleted voters could re-enrol. The BJP accused its rivals of trying to undermine the country's democracy by questioning legitimate electoral processes.

A growing challenge

Opposition parties and supporters of the "cockroach" youth movement have protested almost daily this month, demanding Kumar's resignation over the revision. The youth movement has demonstrated over issues from government school infrastructure to jobs and is described as one of the biggest political challenges to Modi and his BJP in his 12 years in power.

The protests erupted after the Indian Express reported last month that Kumar's two deputies raised several concerns internally about voter list revisions, registration procedures and digital systems.

The CJP said its leaders would meet Delhi police to demand a date for a peaceful protest, and threatened to announce a new call to protest if a date is not given within 24 hours.
