Teams of people are invited to get wet and wear fancy dress in Wiltshire Air Ambulance’s annual It’s a Knockout event.

It will be held on Sunday, July 7, at the Barbury Horse Trials near Wroughton.

Caroline Corrigan, air ambulance head of fundraising, said: “The main theme is giant inflatables and lots of water.

“This is by far the funniest event we arrange annually and we really hope our supporters get together and get involved. Teams can be made of eight to ten colleagues, family or friends, and as long as you don’t mind getting wet then the choice of who makes up your team is yours.”

Challenges include the chicken run and the balloon burst involving water bombs, foam and inflatables.

Each team that signs up can promote its own company. Wilkinson has already signed up three teams.
