New Delhi: Despite offering ‘unconditional' support to United Progressive Alliance, Mamta Banerjee eyes on at least seven cabinet berths in the next government, said sources.

According to the sources, Mamta Banerjee is likely to demand seven cabinet berths and four in the rank of minister-of-state for her party Trinamool Congress in the new council of ministers at the Centre.

If sources are to be believed, Mamta Banerjee was flown-in a charter plane specially sent by Congress President Sonia Gandhi to attend Wednesday's UPA meet at 10 Janpath.

It is worth mentioning here that Mamta talked of giving ‘unconditional support' to UPA while addressing a press conference on Sunday after the results were declared. She said, ‘We are not in favour of political bargaining'. However, she did not forget to mention how she was offered a cabinet berth in NDA regime. She said, ‘During NDA government, Atal Behari sent his emissary Jaswant Singh to my residence and offered me the Cabinet berth.'

Mamta asserted that Trinamool Congress should get a ‘fair representation' in the council of ministers in the UPA government.

In an attempt to keep all its allies satisfied, Congress has devised a formula of ‘one minister, one ministry' for its alliance partners.

Prominent UPA allies like DMK and Trinamool Congress are scrambling for cabinet berths. UPA will decide on formation of the next government at the centre when the allies meet at 10, Janpath here on Wednesday.

It is worth mentioning here that DMK is eyeing on at least seven cabinet berths. Mamta Banerjee's Trinamool Congress is not left far behind. According to the sources, Mamta is likely to put forward her demand for at least seven cabinet berths and four posts of ministers of state. The Railway ministry is likely to remain a bone of contention between the two prominent UPA allies.

UPA will stake claim to form government today after the meeting of its allies gets over.
