Saracens fullback Liam Williams

Wales fullback Williams to rejoin Scarlets

Williams helped English side Saracens to win the Champions Cup and Premiership double last season and was part of the Wales team who won this year's Six Nations Grand Slam.

The 28-year-old is the first major player to announce his departure from Saracens after they were handed a 35-point deduction for breaching salary cap regulations and fined $10 million, a decision the club chose not to appeal.
