Two city councillors have been welcomed to the bosom of the national Conservative Party.

David Cameron, the party's national leader, himself made a parade of this, their second change of political spots in the last year.

This sorry spectacle makes a mockery of the process of popular election. These councillors have shown contempt for those who elected them.

The voters in the city have repeatedly and recently rejected all Conservative candidates.

These two now calling themselves Conservatives have no credibility as Conservatives.

They should now, at once, resign and stand in a by-election. I challenge these turncoats to do that.

Their failure to do so would prove that they dare not face the electors.

This would not surprise me as I have heard already of the understandable anger of the voters in their wards who voted Liberal Democrat and who have no intention of being represented by Conservatives of any hue - whether of the old 'nasty' party or the new policy-free 'hug a hoodie' Conservatives.

Let's have some honesty and integrity from our politicians, including local ones.
