The Six Nations 2023 will see the best international rugby union teams in the northern hemisphere do battle across five rounds between 4 February and 18 March. Ireland start as favourites on the Betfair Exchange while defending champions and Grand Slam winners France come next in the betting. England are third in the market as they begin life under new head coach Steve Borthwick. The good news for Red Rose fans is that their team plays three matches at Twickenham and, with a tricky opener against Scotland followed by the visit of Italy, England have the chance to get points on the board before travelling to Cardiff to play Wales in round three.
