Union railway minister Dinesh Trivedi on Thursday sent his resignation letter to Prime Minister Manmohan Singh, according to TV reports. The PM is likely to accept Trinamool Congress chief Mamata Banerjee’s demand to sack Trivedi. Trivedi came under fire from his own party Trinamool Congress for hiking the fares in the 2012-13 railway budget that he presented on Wednesday.

Trinamool Congress chief Banerjee and party leaders trashed the budget, demanding rolling back of hikes in passenger fares.

Banerjee sent a letter to the prime minister asking him to remove Trivedi and suggested Mukul Roy’s name for the railway minister post, reports suggested.

Trinamool Congress MPs will stage a dharna on Thursday demanding the rollback of railway price hike.
