Shiv Sena leader Arvind Sawant on Monday announced his resignation from the Union cabinet, saying it would not be proper to continue as a minister when a new government is being formed in Maharashtra.

Addressing a press conference, Sawant accused the BJP of reneging on its promise of equal division of seats and power to the Sena and forcing the Uddhav Thackeray-led party to snap ties.

He alleged that the BJP was resorting to 'lies' by denying the agreement reached between the leaders of the two parties before the Assembly elections.

'They have also hurt my party by lying. Since there is no trust left, I have decided to resign,' Sawant told reporters.

He also accused the BJP of hurting the sentiments of the Shiv Sena and of the Thackeray family.

'I have resigned as the Union minister. I have sent my resignation to Prime Minister Narendra Modi,' the Shiv Sena leader said and displayed his letter resigning as the Union heavy industries minister.

Asked if the Sena has snapped its ties with the BJP, he said, 'When I have resigned, you can understand what it means.'

'The BJP had agreed with Sena to equal division of seats and power but it has now refused,' Sawant said.

Sawant also said a new government was in the process of being formed in Maharashtra and it was not proper for him to remain in the Union cabinet and hence he was resigning.

'In such an atmosphere, it is not proper on my part and for the sake of morality to continue as a minister in the Union government,' he said.
