Bill Bryson and Hilary Benn meet street cleaners on South Bank

The minister and the best-selling author met Lambeth Council street cleaners in Belvedere Road, close to the London Eye on the South Bank.

They were joined by Lambeth Council leader Steve Reed and Cllr Sally Prentice, the borough's cabinet member for environment.

Figures published last year show that Lambeth's streets are cleaner than at any time since current records began six years ago

Later in the day, major brands from the fast food, fizzy drinks and chewing gum industries are coming together for the first time with Keep Britain Tidy, government representatives, local authorities, land managers and campaign groups.

McDonalds, Coca-Cola and Wrigleys are among firms forming the partnership with authorities to stamp out litter.

Bill Bryson is president of the Campaign to Protect Rural England which has its offices in Southwark Street.
