Liza Marshall, commissioning editor for drama for Channel 4 television, said the British government had been consulted about whether to go ahead with the Thursday broadcast of "Mark of chain".

"While the channel believes this outcome is unlikely, we are anxious not to add to the extraordinary stresses and concerns they must be experiencing at this time and, in consultation with the writer and producers, we have therefore decided to delay transmission."
The transmission has been rescheduled for May 17, the channel said.
