Prime Minister Manmohan Singh's efforts to reach out to BJP to end the parliamentary stand-off over the missing coal files issue failed tonight with BJP not giving him any assurance on the smooth running of the House tomorrow.

Singh held a meeting with BJP leaders L K Advani, Sushma Swaraj and Arun Jaitley late this evening and requested them to cooperate in the passage of important financial legislations in Parliament but the opposition was unmoved and said it will take a call on the issue after a meeting of its senior MPs tomorrow morning.

Asking the opposition to forget the past, the Prime Minister sought BJP's support in passing of important financial legislations including the Pensions Bill and Securities and Exchange Board of India (Amendment) Bill, sources said.

During the nearly 90-minute meeting at the Prime Minister's residence, BJP maintained it is not responsible for the disruptions in Parliament and accused Congress MPs of causing disruptions.
