Labour launch attack website: Come Clean Colin
ComeCleanColin.co.uk says it aims "bring you the stories Mr Eldridge doesn't want you to see. We will expose this man for his hypocrisy, double standards and dishonesty to you, the electorate.
"You can let us know if you have any more experiences of the man from Bristol, and we'll challenge him to come clean."
But the Lib-Dems have dismissed the professional looking site, which has a companion Twitter feed and Facebook site as desperate.
Tom Morrison, Eldridge's election agent, said: "This is a desperate attempt at smearing the Liberal Democrat candidate. The Labour Party are clearly running scared."
