Kirsty Young's castaway is the former England rugby captain Lawrence Dallaglio.

He was capped 85 times for England, played in three Lions tours and led his club side, Wasps, to the top of the premiership five times.

Yet, he says, he only started playing rugby seriously after the death of his sister, Francesca. She died in the Marchioness disaster on the Thames when he was 16 and her death, he says, blew his world apart.

"Losing my sister was devastating. It made me more determined to do something to bring my parents together. When I first took up rugby, I took it up not for sporting reasons, I needed something to grab onto, I needed an olive branch."
