It's very unlikely that Labour will win but that doesn't necessarily mean the Tories will.
The SNP will probably take at least half of the 13 seats currently held by the Tories in Scotland. They will lose similar amounts to the Lib Dems in the south of England. The decision by the Brexit Party to field candidates in non-Tory seats will make it significantly harder for the Tories to take seats off Labour.
So the chances of Labour winning? Negligible. The chances of the Conservatives winning (a majority)? Not as high as it seems.
