Rajagopal advised the Congress MLAs from coastal Andhra and Rayalaseema to do the same if a similar Bill is introduced in the Assembly.
On resignation by some MLAs in support of united Andhra Pradesh, he said this would not serve any purpose and only reduce the strength of legislators who are opposing creation of Telangana.
Instead of resigning, these MLAs should lead and strengthen the movement against bifurcation of the state, the Congress MP said.
He earlier visited the site of a protest organised by united Andhra Pradesh supporters. Rajagopal asked students and Andhra Pradesh employees, who are opposing statehood to Telangana, to persuade MPs and legislatures to announce their open support for unified Andhra Pradesh.
