As UPA completes three years in office, BJP on Tuesday claimed the government may fall anytime as coalition partners were unhappy and were not even ready to break bread together.

During a discussion on the issue at the party's Parliamentary Party meeting here, BJP while referring to Trinamool Congress leader Mamata Banerjee refusal to attend a dinner hosted by Prime Minister Manmohan Singh, said the three years of UPA regime would be written in "black letters."

"Its allies are not happy with it. A leader of the ally party does not even want to eat food together. You can imagine the state of affairs... The UPA is not even in a position of eating snacks.

"I wonder what would be the flavour of the dinner hosted to celebrate the three years of completion of government," said BJP spokesman Shahnawaz Hussain after the party's meeting.

He said, "The completion of three years of UPA regime will be written in black letters."

Hussain said, "This government can anytime...(fall). The government claims to have a total majority of 272, but the actual figure seems 227 as even its allies are not happy with it."

The party also discussed the "failures" of the present regime, he said. Party leader L K Advani patted the back of MPs for their good performance during the Budget Session of Parliament, he said.

"The party has been able to put the government on the backfoot on many occasions during the current session," said Hussain.
