Labour MPs may soon become an endangered species. The SNP took all of them out in Scotland - except one - at last year's general election, and the Tories' takeover of southern England left the party with little to fall back on except its northern heartlands. They won't be able to rest easy there, as Ukip is coming for them.

The party's new leader Paul Nuttall has made it his mission to "replace the Labour Party and make Ukip the voice of patriotic Britain". He hopes his focus on the North and Midlands will mean Ukip can win seats "running into the double figures" at the next general election. And thanks to Jeremy Corbyn, he can expect to do rather well.
