A simmering rivalry between two Midland politicians has erupted again after Worcester MP Mike Foster challenged his equivalent in a neighbouring constituency to stand against him in the General Election.
Mr Foster laid down the challenge to Peter Luff, who represents neighbouring Mid Worcestershire, in a bid to settle their feud once and for all.
But last night Mr Luff said he had no intention of abandoning his own constituency.
The bad- tempered relationship between the politicians has seen them clash in the House of Commons over issues such as education, police reform and health.
Although they represent different parties - Mr Luff is a Conservative and Mr Foster is Labour - the bad blood between them goes beyond anything normally seen in British politics.
In one frank exchange of letters, Mr Luff accused his rival of talking "garbage".
Mr Foster responded by telling him to "calm down and look at what I said", adding "if you had done so, perhaps the battered teddy would not have found itself once again flying out of the cot."
The feud came to a head when Mr Luff mentioned a school in Mr Foster's constituency, in a Commons debate.
The Worcester MP issued a furious statement challenging his adversary to a fight to the finish in a General Election.
Mr Foster said: "It is not too late - make my day Peter and stand again in Worcester as it clearly matters more than your own constituency."
Mr Luff responded: "I know it is difficult for Mike, but he could try sensible political debate rather than making cheap points."
