Channel 4 News reportedly cancelled an interview with Prince Charles after being asked to sign a contract with “North Korea"-style conditions.

The Independent has today reported the Prince of Wales’s 15-page media contract states that he should have advance knowedge of precise questions and interviewers "may solely ask questions" previously approved by Clarence House. It also states that the Prince has the right to oversee editing and the power to block a broadcast altogether if he does not approve of the final product.

The newspaper reports that the Prince will only speak to broadcasters if a contract is signed. This, it reports, led to the cancellation of an interview due to be conducted by Channel 4 News presenter Jon Snow on Sunday.
