MP Tim Yeo who is chairperson for parliaments Energy Select Committee has been dropped as candidate for the next election by his local Conservative party.
The South Suffolk Conservative Association voted against re-adopting him in secret ballot on Friday.
Yeo now has to decide whether to accept the decision, appeal against it or re-apply in a new selection process.
In a statement the association said: “Mr Yeo is now considering his position and will advise the Executive Council of his intended course of action.”
They refused to make any further comments until Yeo has reached a decision.
Jon Ashworth MP, Labour’s Shadow Cabinet Office Minister said: “Tim Yeo’s deselection is another sign that under David Cameron the Conservative Party is reverting to type, with no place for those who thought he meant it when he said ‘Vote blue, go green’.
“Just this week one Tory with modernising credentials has been deselected and another has quit and David Cameron is trying to water down a green levy he introduced and even boasted about.”
Last month Mr Yeo was cleared of breaching of the lobbying rules for MP’s after he was covertly filmed by Sunday Times reporters posing as representatives of a green energy firm. In the video he appeared to say he would he would take money to approach ministers on behalf of their fake firm.
