Tory grandee David Mellor has claimed Labour's fate was sealed the moment Jeremy Corbyn was elected.
The results from the local election show Labour has lost control over a number of strongholds in Lincolnshire, Warwickshire and Cumbria.
The party has also lost seats in the local councils of Blaenau Gwent and Bridgend.
In an interview with Paul Ross, Mellor, the former MP for Putney who now works as a broadcaster, said "Labour have written their suicide note with Jeremy Corbyn."
He also condemned Angela Merkel for supposedly allowing her ministers to support figures in the EU keen to "hold the gun to the head of Britain" and humiliate the country over the supposed £85bn pound bill.
