Ditch the tiresome turncoats.
Most notably, it happened in 2008 when the gone and now forgotten Croxteth Independent Nadia Stewart switched to the Lib-Dems on election night, keeping Corporal Wearing Badley and co in power under false pretences.
The year before, Stewart had also quit the Labour party.
Then there was Wirral councillor Denis Knowles who crossed the floor from Labour to Conservative, and is up for re-election in May.
And now Sefton Tories find themselves similarly afflicted, with former mayor Alf Doran defecting to UKIP.
What all these pretenders need to realise is that they were voted into office on a fixed ticket: not a voucher which could be exchanged at personal whim for some other political booty.
They should step down with immediate effect, not hang in there with the delusion that they were voted for as endearing individuals irrespective of party.
