Netflix chiefs are said to be exasperated by the decision of the Duke and Duchess of Sussex to give bombshell interviews to rival television networks – despite having a multi-million-dollar deal with the streaming giant.

The Mail on Sunday understands there was 'a real sense of annoyance' when Prince Harry last month revealed details of his meeting with the Queen at Windsor Castle during an interview with NBC.

According to a source, that frustration was heightened because a Netflix film crew was shadowing Harry at the time for Heart Of Invictus, a documentary about his event for wounded and injured service personnel and veterans.

'Netflix would have loved the first comments about the visit to the Queen for the documentary,' said the insider. 'There was a real sense of annoyance that they were made to another broadcaster.'
