Ruling out any differences between Congress and Nationalist Congress Party (NCP), Union Health Minister Ghulam Nabi Azad today said Sharad Pawar is the biggest "supporter" and "well-wisher" of UPA II.

"There are no differences with Sharad Pawar. He is the biggest supporter and well-wisher of the UPA," Azad told reporters on the sidelines of a function here.

When Trinamool Congress chief Mamata Banerjee left UPA II, Pawar was the first to come out and strongly condemn the move, Azad said, adding, "It signifies how strongly he feels that UPA should last for the full term".

Azad's reaction comes a day after Pawar's nephew and Maharashtra deputy chief minister Ajit Pawar resigned following allegations of an irrigation scam when he was the state's Water Resources Minister.

Congress and NCP are ruling the coalition in Maharashtra as well.

Azad said there is no threat to the state government as the deputy CM resigned on allegations of a scam and not because there were any differences.

"Ajit Pawar has not resigned because he has any differences either with the state or the central Congress, but because there are some allegations. He has said he would not accept any post till his name is cleared," Azad said.

Meanwhile, putting to rest speculation on a change in his portfolio, Azad said he is happy being the health minister.

"There will be no change in my portfolio. I am happy being the health minister. Health of the people of the country is my priority," he said.

On the question of Telangana, Azad said it is a complex issue and the central government wants an amicable solution.

"It is a very complex issue. Whenever we have tried to solve it, it becomes more complex. There are many parties to it. We want a solution that is agreed by all," Azad, who is AICC general secretary in-charge of Andhra Pradesh, said.
