Former England rugby captain Lawrence Dallaglio has signed with BT Sport to become its leading rugby union expert, where he'll commentate and be a studio pundit for coverage of live rugby matches from the Aviva Premiership when the channel launches this summer.

Dallaglio is also to become a BT ambassador, following in the footsteps of London 2012 stars such as the Brownlee brothers and Jonnie Peacock. Jake Humphrey and Clare Balding have already been announced as presenters.
