Litter louts are most likely to dump Coca-Cola cans, Cadbury wrappers and Walkers crisp packets, a survey has revealed.

The branded packaging was found strewn across parks, beaches and river or canal banks during a national litter-picking exercise.

Volunteers scooped up more than 37,000 pieces of rubbish in the latest Keep Britain Tidy campaign, more than 10 times the quantity picked up in previous years, according to the charity. Other frequently dumped brands were McDonald's, Mars and Red Bull.

Phil Barton, chief executive at Keep Britain Tidy, said: "These results should be a wake-up call that we all need to do more to love where we live. Litter is not just an environmental problem. It affects perceptions of safety and costs nearly £1 billion a year to clean up.

"This survey gives 37,000 reasons why we all need to do more to make littering socially unacceptable – to reduce the environmental, social and financial costs of this national problem."
