Labour has vowed there will be "no pacts" with the Liberal Democrats or the SNP at the next election as panicking Tories accused opposition parties of secret alliances.
Shadow Foreign Secretary David Lammy said he sees "no possibility" of Labour making a formal alliance with the Liberal Democrats and argued that voters don't want "politicians to stitch up deals in the corridors of power".
Conservatives have tried to shift blame for their double by-election defeat onto opposition parties, with Health Secretary Sajid Javid urging Keir Starmer and Ed Davey to "come clean" about electoral pacts.
