Cronyism fears as businessman Sir Ian Cheshire is named head of Channel 4

Jon Snow and other leading broadcasters express concern over appointment and call for C4's public service remit to be protected

Ministers have been accused of another case of cronyism over the appointment of the new Channel 4 chair. Veteran businessman Sir Ian Cheshire has been chosen to oversee the broadcaster, which has been beset with rumours that it faces privatisation.

Cheshire, former chief executive of Kingfisher, the B&Q owner, served on a business taskforce for former prime minister David Cameron. He also oversaw the selection process under which Tory donor Ben Goldsmith was appointed to the board of the Department for Environment, Food and Rural Affairs. He is chairman of Goldsmith's investment firm.
