Kolkata: Former union finance minister Yashwant Sinha on Tuesday slammed the Union Budget, saying the government had made promises in the style of an election manifesto without creating provisions for achieving them.

It is not clear from the budget documents how the government will provide for various targets and programmes, Sinha said in Kolkata.

Whereas the government has committed to double agricultural income by 2022, farm income has over the past four years declined by 1.38%, the rebel BJP leader said.
