Remember the Labour slogan before the council election? "Send Cameron a message" they urged. Voters once again believed that voting Labour would mean defeating the Tories, regardless of whether there was a Tory standing in any particular ward.
Imagine how those anti-Tory voters are going to feel when they find out that Labour's group on Wrecsam Council has stuck up two fingers to the electorate and done a deal with the Tories that gives them a Lead Member portfolio in return for "an understanding" on key votes.
This deal was struck, it seems, because Labour didn't want to be totally at the mercy of their coalition partners, the Democratic Independent Group.
