Union agriculture minister and NCP chief Sharad Pawar withdrew on Monday from the empowered group of ministers on telecom that was slated to decide the 2G spectrum pricing.
In a letter to PM Manmohan Singh, Pawar justified his decision: "Attempts were made in the past to drag me in the 2G spectrum controversy." Sources in the government said the PM had accepted his resignation.
Last year, Pawar left the group of ministers on corruption that drafted the Lokpal Bill after social activist Anna Hazare levelled corruption charges against him.
The PM had specially asked Pawar to head the telecom EGoM after its former chairman, finance minister Pranab Mukherjee, stepped down to fight the presidential poll.
The first meeting of the EGoM under Pawar's leadership was scheduled on Monday.
