but I know how important a competition this is and we all want to get behind Wales, so I've decided to break with tradition on this occasion and fly the flag for Wales in Downing Street on Saturday."

We would only usually fly a home nation flag for a final, but I know how important a competition this is and we all want to get behind Wales David Cameron, Prime Minister

The idea was raised earlier on Wednesday by Cardiff West MP Kevin Brennan at Welsh questions.

He pointed out the Flag of St George had been flown when England had been involved in big sporting events.

Welsh secretary Cheryl Gillan promised to speak to Mr Cameron about it.

Mrs Gillan also paid tribute to the Welsh rugby team's success describing it "asone of the best adverts for Wales".

Earlier, a group of MPs congratulated the Wales players by tabling a Commons motion.

In it, they noted that the team's success so far was "achieved by its exhilarating, exemplary, professional and disciplined approach led by its outstanding captain Sam Warburton and its coaching staff led by Warren Gatland".
