Dan Biggar is leaving Ospreys at the end of the season.

The Wales and Lions playmaker will join Premiership side Northampton Saints next season.

The 27-year-old will move to Franklin’s Gardens in the summer of 2018 after completing this season with Ospreys.

Biggar has won 56 caps for Wales and was a member of the British & Irish Lions squad in New Zealand this summer.

“We’re delighted to have secured the signature of such a highly rated player,” said Saints director of rugby Jim Mallinder.
