The Lib Dems are hoping to boot Tory heavyweights Theresa May, Jeremy Hunt and Michael Gove out of office at the next general election.
The trio's constituency are on a 20-strong list of targets the party thinks are winnable after a strong showing at the polls last week.
This morning Lib Dem leader Sir Ed Davey said he's "spent my life" fighting Tories - and won't go back into Government with them.
