Schoolchildren will be joined by Wimbledon champion Andy Murray's mum Judy in an attempt to break the world record for the largest tennis lesson, today.

As part of Hounslow's second tennis festival, around 500 children from 48 primary schools in the borough will take part in 628 mini tennis matches in the hope of breaking the Guinness World Record.

The event will be held with the Scottish tennis coach at Dukes Meadows Tennis Centre in Chiswick, today (2).

Ms Murray previously helped set the current record of 405 people in March 2014 in the USA, and Hounslow hope to smash this with 750 people including teachers, sports leaders and guests.

Last year, the first festival saw Hounslow's schoolchildren successfully break the Guinness World Record for the most people bouncing balls on tennis racquets at the same time.

In November 2013, students from The Heathland School were winners of a Guinness World Record poll which asked people to vote for their record of the week.
