RUGBY superstar Billy Vunipola will be in Oxford today to sign copies of his new book Wrecking Ball.

The memoir chronicles the England stars 10,000 mile journey from the tiny Tongan village of Longo Longo to the imposing vastness of Twickenham.

Standing at six foot two inches and weighing almost 20 stone, he is a rampaging and unmissable presence on the rugby pitch, for both club and country.

He will be signing books at Blackwell's Westgate store from 6pm.

Those attending are advised to arrive early.
