Tory MP Tim Yeo is fighting for his political career after his local party apparently refused to re-adopt him as its candidate for the next general election.
Mr Yeo, who was recently reinstated as chairman of the influential Commons Energy Committee after being cleared of lobbying allegations, is said to be "considering his options" following the decision by the South Suffolk Conservative association.
A statement from the South Suffolk Conservatives said: "The Executive Council of the South Suffolk Conservative Association met on the evening of Friday 29th November and voted not to re adopt Tim Yeo for the 2015 General Election
"Mr Yeo is now considering his position and will advise the Executive Council of his Intended course of action."
Mr Yeo, 68, who served as environment minister in John Major's government, has represented the constituency for three decades, and won an 8,600 majority in 2010.
In June he was caught up in a newspaper sting and faced allegations that he offered to lobby ministers and 'coached' a business associate who was due to give evidence to his committee.
However, the cross-party standards committee found he had done nothing wrong.
