Taking a cue from the fitness challenge gone viral on Twitter, Congress President Rahul Gandhi on Thursday dared Prime Minister Narendra Modi to bring down petrol and diesel prices or face country-wide agitation.

"Dear PM, Glad to see you accept the @imVkohli fitness challenge. Here's one from me: Reduce fuel prices or the Congress will do a nationwide agitation and force you to do so.

"I look forward to your response," Gandhi tweeted with the hashtag #FuelChallenge, a fitness campaign where people post their exercise regime on social media and challenge others to do the same.

Dear PM,

Glad to see you accept the @imVkohli fitness challenge. Here’s one from me:

Reduce Fuel prices or the Congress will do a nationwide agitation and force you to do so.

I look forward to your response.#FuelChallenge
