England rugby legend Lawrence Dallaglio will be among the campaigners taking part in the Save Barn Elms Rally and Family Fun Day this weekend.

The rally, at the popular playing fields on Saturday, July 16 between 10am and 4pm, has been organised to help save the fields and riverside nature spots from being used as a giant excavation and waste transfer site for seven years as part of the Thames Tunnel project.

Several famous faces will be there to support the campaign alongside event organisers Wandsworth and Richmond Councils, residents' pressure group Stop the Shaft, MPs Justine Greening and Zac Goldsmith and GLA members Richard Tracey and Tony Arbour.

Access to the playing fields is from Putney Embankment or Queen Elizabeth Walk, with the main rally event taking place at 11.30am.

A range of sports taster sessions will be going on all day to give residents the opportunity to try out the activities which take place at Barn Elms every week.

There will also be live music and a range of fun activities for young children, with food and light refreshments also available.

Councillor Ravi Govindia, leader of Wandsworth Council, said: "If you believe that London's green open spaces should be protected from major construction work then please come and join us at Barn Elms on July 16th. This event is all about showing Thames Water how much we all care about our playing fields and riverside walk."
