Anyone throwing away litter at one of 25 rubbish bins soon to be installed across Westminster can expect a burst of song, the blast of a trombone or a celebrity congratulating them for waste disposal.

They are being brought to the streets by Keep Britain Tidy's Love Where You Live initiative, which aims to change people's bad littering behaviour behaviour and encourage them to take pride in their area.

The bins will be ready to give out back chat from October 13, and will remain in London for two months after which they will tour the UK and return for the Olympic Games next summer.

If successful, the bins will become a permanent fixture.

Councillor Ed Argar, Westminster Council's head of city management, said: "We want to do everything we can to encourage people to dispose of litter correctly when they are out and about in Westminster.

"We hope that this project will do just that and what is a fun stunt helps draw attention to a very serious issue.

"It is all of our responsibilities to get rid of our rubbish and do the right thing."

The project has been produced in partnership with arts organisiation Sing London.
