Chennai: Launching a scathing attack on the Election Commission of India for cutting short the campaign period in West Bengal, DMK chief M K Stalin on Thursday backed Trinamool Congress saying the EC has one set of rules for the opposition and another for the ruling party.

"Ban on campaign in nine constituencies in #WestBengal. The EC has one set of rules for the opposition and another for the ruling party. Highly condemnable," he tweeted.
