Norwich Union has warned youngsters to beware of errant forehands, and pay less attention to summer fruits.

As Wimbledon fever takes a grip, the insurer has urged consumers to “forget strawberries and cream,” and pay heed instead to “Federer fever”.

Last year the insurer payed out a cool £4.3m in claims for 5.4 million square metres of broken glass – enough to span the railway from Land’s End to John O’Groats.

It adds that over the summer months claims rise by 20% as a result of “energetic youngsters trying out their latest techniques on their own lawns”. Let’s hope they’re talking about the ball game played at SW19.
