A Tory-Lib Dem coalition sounds doubtful, but so do most options. BBC:
Senior Conservatives and Liberal Democrats are to hold more talks about the possibility of their parties forming a new government.
Conservative and Lib Dem negotiators will meet at 1100 BST - after leaders David Cameron and Nick Clegg met on Saturday for private 70-minute talks.
There will also be a meeting of Conservative MPs at 1800 BST on Monday, the BBC understands.
The Tories won the most election votes and MPs, but are short of a majority.
