Saracens sign Vunipola duo

SARACENS have secured the surprise double signing of Wasps No8 Billy Vunipola and Harlequins prop James Johnston for next season.

Samoa international Johnston won the Premiership with Quins last season while Vunipola has shone for Wasps since his debut in 2011, and earned a place in England’s Saxons squad last week.

Vunipola, 20, will join up with his brother Mako, who is one of a dozen players to agree new contracts at Saracens, including England winger David Strettle and scrum-half Richard Wigglesworth.
