The final MRP poll from Survation puts the Lib Dems and Tories within a gnat's whisker of each other.
Sam Freedman says:
'“If any doubt arises as to which is or was at any material time the party in opposition to Her Majesty’s Government having the greatest numerical strength in the House of Commons, or as to who is or was at any material time the leader in that House of such a party, the question shall be decided for the purposes of this Act by the Speaker of the House of Commons, and his decision, certified in writing under his hand, shall be final and conclusive.”
So if one party is clearly ahead then their leader is LOTO. But if it’s more complex - say, the Tories won 75 seats and the Lib Dems 73, and then two Alliance MPs from Northern Ireland said they’d sit with the Lib Dems - well the Speaker will have to get involved and make a call.'
The thought of the Tories losing so badly that they don't even get to be the official party of opposition is within our grasp.
I've heard that the Lib Dems now think they have a chance of winning places like Witney where they didn't think they had a hope at the start.
