Today, writing to Andrew Speed, the chairman of the Bury St Edmunds Conservative Association, Mr Ruffley said: "Sadly, although I have apologised for a very regrettable incident last March and both my former partner and I considered the matter closed, I have reluctantly come to the conclusion that a protracted media debate on my private life, whatever the motivation or however misinformed, would not serve the wider interests of the Conservative cause in East Anglia.
