A “progressive alliance” between Labour, the Liberal Democrats and Greens would fail to stop Theresa May securing a strong majority even if it agreed to run a single candidate in every seat, a new analysis has revealed.
Some figures from all three parties have backed the idea of cooperating to increase the chances of a soft Brexit and ensure that the Conservatives do not secure a landslide. It comes as supporters of the idea prepare to gather for a major event on Monday championing the idea.
However, an analysis based on the latest polling suggests that even the most comprehensive and successful alliance between the three parties would still lead to a comfortable Conservative majority of 64 seats. There would need to be a 10% swing towards the alliance’s candidates compared with the current polling for the three parties to secure a majority between them.
