Labour has a long road ahead of them; they are 124 seats away from a majority. It's just a guess, but I don't think even a 10 pt uniform swing would get them 124. Their loss of Scotland makes things even harder; even in 2010, Labour had 217 seats outside Scotland; today Labour has 201. Barring a Scotland rebound, they would need to gain 124 in England and Wales alone...
Meanwhile, as an election nerd, I hope Johnson's gov't adopts the 600 seat redistribution; it would be cool to see new maps, especially for more even apportionment.
As I've said, Labour doesn't need to win an overall majority, or even win more seats than the tories to get into 10 Downing Street.
They just need to make it so Labour+SNP is a majority. Assuming the SNP keeps 40 seats or so, that means Labour needs roughly 280 seats or so. Still an uphill climb, but not a net pickup of 120+ seats and a 10 point lead nationally anymore
