Kamat had been warned by his party that if he skipped today’s swearing-in ceremony, he would have to exit as minister. He obliged on both counts.

Kamat was given independent charge this morning as Minister of State for Drinking Water and Sanitation. He was reportedly upset that he had not been given a Cabinet rank.

However, in a press release, he said, “There is no question of any disappointment over the Portfolio, which is itself an important one, with concerns related to requirements of a large sections of the people of the Country. The reasons are totally personal and not any defiance of the Party Leadership as is being made out in certain sections of the media.”

Mr Kamat is from Mumbai. The ministry he was assigned to today has been carved out of the Rural Development Ministry.

Till this morning he was Minister of State in the Ministry of Home Affairs and Minister of State in the Ministry of Communications and Information Technology.

Another Congressman, Srikant Jena, who is from Orissa was also upset about not being given Cabinet rank.

Mr Jena has been made Minister of State with Independent Charge of Statistics and Programme Implementation.
