Wales will now welcome France at the Millennium Stadium on Saturday with a second Grand Slam in three years on the line.
Murrayfield hosted the biggest surprise of the weekend as Scotland defeated England with Gloucester's Chris Paterson scoring 12 of Scotland's 15 points. Even a world record breaking performance by Jonny Wilkinson who became the highest points scorer in test history was not enough for the English.
