Downing Street "does not support" Isle of Wight MP Bob Seely's proposal to bring legislation that could strip the Duke and Duchess of Sussex of their royal titles.

No 10 said Rishi Sunak does not back Tory MP Mr Seely’s plan, and also dismissed a government minister’s call for a “boycott” of Netflix over its documentary on Prince Harry and Meghan Markle.

The couple have received criticism over the six-part series for apparently attacking British institutions as they discussed their experiences including racism.

Employment minister Guy Opperman described them as “clearly a very troubled couple” but said they had faced “unacceptable” press intrusion.

“I would urge everyone to boycott Netflix and make sure that we actually focus on the things that matter,” he told BBC Question Time.

But a Downing Street spokesman told journalists “it’s a matter for the public what channels they want to watch”.

Conservative backbencher Mr Seely suggested he could bring forward a short private members’ bill in the new year that could give the Privy Council the power to downgrade their status.

He told the PA news agency there is “a political issue” with the couple, adding: “As well as trashing his family and monetising his misery for public consumption, he is also attacking some important institutions in this country.”

But the No 10 spokesman said “we do not support” the proposal.

Harry and Meghan signed lucrative deals, thought to be worth more than £100 million, with Netflix and Spotify after quitting as senior working royals.

The first three episodes of a six-part Netflix series are available to stream, with the rest coming on Thursday.

So far, Harry has accused the royals of having a “huge level of unconscious bias” and Meghan alleged that the media wanted to “destroy” her.
