Tewkesbury's Zac Purchase recorded a second consecutive win in the lightweight men's double sculls in the Rowing World Cup on Sunday.

Purchase and Mark Hunter took GB's only gold medal at the meeting in Lucerne after winning in the previous meet in Munich last month.

Their performance impressed Sir Steven Redgrave: "Zac and Mark are only going to get better," he said.

"The field is different to last year's competition, but they are a class act."
