New polling has delivered a major blow to Jeremy Corbyn’s Labour, with the party apparently suffering in its traditional strongholds.
The Conservatives have also endured polling slumps in the new YouGov data, though they are nowhere near as pronounced as Labour’s.
Ahead of next month's general election, Mr Corbyn’s troubles are most visible in Labour’s northern heartlands.
In the north-west, the party scored 30 per cent, down 25 from its 2017 general election result. Boris Johnson’s Tories are polling at 33 per cent.
There was a similar drop in support in the north-east, where Labour polled at 32 per cent, down 23 from 2017.
Even in London there was a sizeable drop for Labour, which is down from 55 per cent in 2017 to 39 in the latest data, which was gathered from October 17 up to Monday this week.
Meanwhile, in Tory strongholds in the south-east and south-west, there were identical 13-point drops to 41 per cent.
The Liberal Democrats and newly formed Brexit Party appear to be taking advantage of the polarised Brexit debate, with the arch-Remainers led by Jo Swinson increasing support in every region.
The Lib Dems’ biggest leaps came in the north-west (up from five per cent in 2017 to 17 per cent in the latest polling) and south-east (up from 11 per cent in 2017 to 23 per cent in the poll).
The Brexit Party’s biggest support is coming from the north-east, where it is currently polling at 19 per cent: seven points behind the Tories.
