Simon Danczuk MP has dismissed Jeremy Corbyn's election as Labour leader as an 'experiment' that will go wrong and said voters in his constituency will now turn their backs on the party.
In his only TV interview, the Rochdale MP told Granada Reports Jeremy Corbyn was 'on a temporary contract' and he only has a matter of 'weeks and months' to prove he is up to the job.
"When I was out knocking doors (in Rochdale) a few weeks ago testing views on Jeremy, people weren't enthusiastic about him at all," said Mr Danczuk.
"Not a single person (I spoke to) believed they would support Labour if he was the leader. That's why I have concerns about it."
While North West MPs like Barbara Keeley, Andrew Gwynne and Bill Esterson, who all voted for Andy Burnham, called for unity following the result, Mr Danczuk immediately placed pressure on Labour's new leader to perform well at Prime Minister's Questions, compromise on his 'left-wing views' and appeal to the public on issues such as defence.
The Rochdale MP, who voted for Liz Kendall in the leadership contest, also heavily criticised Mr Corbyn's acceptance speech, which he described as 'insular' and said 'clearly shown for him it's politics as normal' and 'didn't reach out to the wider public.'
The veteran left winger got almost 60% of the vote in the contest, beating Leigh MP his Andy Burnham into second place.
