pbr Conservative and Liberal Democrat negotiators are resuming talks that could break the deadlock of the hung parliament and see David Cameron finally installed as prime minister.br ppbr On Sunday night, The Tory leader held his second face-to-face talks with Nick Clegg in the space of 24 hours, meeting behind closed doors in Parliament.br ppbr It followed a marathon session, lasting more than six-and-a-half hours, between the Conservative and Lib Dem negotiating teams in an attempt to hammer out a deal on co-operation in a new government.br ppbr The negotiating teams are meeting again to discuss "specific proposals." However, Mr Cameron faces a potentially tricky meeting with his MPs at Westminster as he addresses them on the discussions. Many remain deeply hostile to the idea of an agreement with the Lib Dems - particularly if it involves giving ground on the crucial issue of reform of the voting system.br ppbr But even as the two opposition parties edge closer to an agreement, it appears that Gordon Brown has not given up his slender hopes of retaining Labour's grip on power. It has emerged that the Prime Minister slipped out of No 10 for a secret meeting with Mr Clegg in the unlikely setting of the Foreign Office.br ppbr The focus remains firmly on the Tory-Lib Dem discussions though, with neither side giving much away about what was being said.
