Stanley Johnson is a veteran author, environmentalist and politician - and father of Boris Johnson, the London mayor.

Stanley's career has seen him write successful thrillers, confront seal-clubbers on ice floes and be hailed by Greenpeace.

He has also worked for the World Bank, the United Nations, the European Commission and John D Rockefeller.

While his work has taken him all over the world, Stanley has always kept his strong links with Exmoor, where he still manages the family farm.
