Celebrities descended on Victoria Park to lead an army of volunteers transforming a derelict building and yard into a community garden and classroom for children to learn about ecology.

Pop duo Jedward joined ex-Eastenders stars Nicola Stapleton and Joe Swash, along with ex-glamour model Melinda Messenger and builders expert John Russell from the TV show Cowboy Builders for the P&G Capital Clean Up last Saturday.

They spent more than eight hours clearing weeds, removing debris, painting fences and planting flowers.

New tarmac was laid and a mural of urban art was created for the front of old storage sheds, and a garage was transformed into an indoor facility for children to store their belongings.

Victoria Park development officer Dave Hime, who helped organise the event, said: “It was overwhelming to see how everyone worked so hard together to turn this old derelict area into a place that will be well used by the community as a whole.”

The clean-up was part of a three month programme, run in partnership with The Greater London Authority, to help London look its best for next month’s Olympics and beyond.

The clean up will be aired on Channel 5 on June 23.
