"Why is he (prime minister) sending Union ministers, (who) will go and speak ill against the states? This is something which is unbecoming of a minister. The prime minister should take note of this and stop this exercise," he told reporters here.
"They are vitiating the environment of our democracy. The federal structure is being undermined. This is a reflection of their immaturity in governing this great nation," Sangma said.
Sangma also took a dig at Union Tourism Minister Alphons Kannanthanam, who visited Meghalaya without informing him and later, criticised the state for its "failure" on several fronts.
"A Union minister, when coming to a state, should send a letter to the chief minister first, inform him of his programme schedule and after that, if he wants to meet his party leaders, it is fine," he said.
