RLD has three MPs in the Lok Sabha and its support to the UPA is crucial in the confidence vote.

After a meeting of the Union Cabinet, Finance Minister P Chidambaram told reporters that the decision to name the airport at Amausi as 'Chaudhary Charan Singh Airport' will honour the sentiments of the people and will also be a befitting tribute to the late Prime Minister.

Asked about the timing of the decision ahead of the trust vote, Chidambaram said a request from the Uttar Pradesh government was pending for quite some time and the cabinet meeting chaired by Prime Minister Manmohan Singh took the decision.

He said Chaudhary Charan Singh was as eminent freedom fighter and farmers' leader.
