The Football Association have charged Luton manager Mike Newell with improper conduct following controversial comments he made after the match against QPR last month.Newell`s remarks related to assistant referee Amy Rayner. He also questioned the role of women match officials in football. Newell has until December 21 to respond. A statement on the FA website read: 'Newell has been charged with improper conduct to the extent that his comments related to assistant referee Amy Rayner personally, and with failing to act in the best interests of the game in that his comments were made about the role of women match officials in football generally.' Speaking after the game, which Luton lost 3-2, Newell said: 'She [Raynor] should not be here. I know that sounds sexist, but I am sexist, so I am not going to be anything other than that. 'We have a problem in this country with political correctness, and bringing women into the game is not the way to improve refereeing and officialdom. 'It is absolutely beyond belief. When do we reach a stage when all officials are women, because then we are in trouble? 'It is bad enough with the incapable referees and linesmen we have, but if you start bringing in women, you have big problems. 'This is Championship football. This is not park football, so what are women doing here? It is tokenism, for the politically-correct idiots.'
