The top government source, however, refused to say what kind of changes Manmohan Singh would bring in the cabinet.

Pawar, who last week assumed charge as president of the International Cricket Council, also holds additional charge of food and consumer affairs and public distribution.

"It is up to Pawar to decide which portfolio he wants to retain," the source told IANS, adding the ministry Pawar opts out of would be given to a Congress MP. "Discussions regarding this have begun in the Congress."

The Nationalist Congress Party chief had met the prime minister Monday and said he wanted to devote more time to do party work.

The prime minister assured him that the matter would be discussed with him at an "appropriate time".

Currently, K.V. Thomas is the only minister of state to assist Pawar in both the ministries.

Pawar, who came under fire from the opposition in parliament over the rising food prices, said he had asked the prime minister six months ago to relieve him of some of his ministerial duties.
