Dan Biggar's second-half try helped Wales to a 20-13 victory over France in Paris and kept alive their hopes of winning the Six Nations.

Leigh Halfpenny kicked the 2013 champions into a 6-3 lead as the Welsh tried to control possession and the hosts struggled to threaten in attack.

France, who were beaten by Ireland a fortnight ago, thought that they had taken the lead when winger Yoann Huget crossed over in the corner, but final pass was adjudged to be forward.

Wales continued to enjoy possession, but the home side had chances to edge in front as both fly-half Camille Lopez and Clermont Auvergne teammate Morgan Parra missed penalties either side of half time.

Midway through the second half, Wales scored the crucial try as scrum-half Rhys Webb found a gap before forward Dan Lydiate's offload presented Biggar with the chance to score in the corner.

France hit back when full-back Brice Dulin touched down to reduce the arrears as Philippe Saint-Andre's team tried to produce a late fightback.

However, weaknesses in the French scrum led to another Halfpenny penalty and a famous Welsh victory in Paris.
