Keir Starmer has explicitly ruled out "any" deals between Labour and the Liberal Democrats at the next election.
The Labour leader said he wouldn't form a coalition with "anyone" and also insisted his party would not enter into a looser "confidence and supply" agreement.
Mr Starmer recently rejected the prospect of a pact with the SNP but he was less explicit on Sir Ed Davey's party, which has been making gains in Tory heartlands.
