 Wales seized their 20th Triple Crown in dramatic fashion after a hugely controversial ending to a gripping contest at Twickenham.Scott Williams' brilliant steal, kick-ahead and try with five minutes remaining put Wales ahead for the first time after four penalties apiece from Owen Farrell and Leigh Halfpenny had the teams locked together at 12–12.With time up, replacement Mike Brown put David Strettle over on the right but after several minutes of deliberation, television match official Iain Ramage ruled the winger had failed to ground the ball.
