Who was a modern writer in England who had contract on his life by national government for writing novel?

There's no widely known instance of a modern English writer having a contract *on their life* from the national government for writing a novel. Governments might censor or suppress writing, even imprison authors, but a formal "contract on their life" for writing a specific novel is highly improbable and lacks historical precedent in modern England. Such a scenario would be more likely to occur in a totalitarian regime, not a democracy like the UK.
