The Queen has received hundreds of messages of support in the wake of Meghan Markle and Prince Harry's controversial interview with Oprah Winfrey.

Her Majesty, 94, is understood to be "pleased" after being inundated with letters of encouragement in response to the Duke and Duchess of Sussex's accusations against the Royal Family during the two-hour TV special earlier this month.

The couple claimed an unnamed royal was "concerned" about the potential colour of - then unborn - son Archie's skin due to Meghan's mixed race heritage.

Since the interview premiered in the US on March 7 - and the UK the following night - well-wishers have also flooded Windsor Castle with cards and gifts in a sensation show of solidarity, the Express reports.

A royal source told the Mail On Sunday: “We have seen a spike in correspondence after the interview in the same way that it might spike after any other event.”

They said that some of the responses are “deeply” personal - with the Queen’s ladies-in-waiting replying to every letter.

The news emerged as the fallout from Megxit continues to engulf the Royals.

Despite claiming to step back as senior royals to enjoy a “private life”, the Sussexes saw fit to take part in the tell-all interview earlier this month.

The allegations levelled at the historic institution have created its biggest scandal since Princess Diana divorced Prince Charles in the 1990s.

The rift between the Sussexes and the Royal Family has intensified since the interview aired earlier this month

But it appears that despite firing the first shot, the assault has backfired on the couple - currently living in an LA mansion.

A YouGov poll found that Harry and Meghan's popularity plummeted after their interview, while the Queen's remained high.

During the explosive interview, Prince Harry claimed that Prince William and Prince Charles were “trapped” in the Royal Family.

Royal sources have since dismissed his outlandish statement.

A snap poll earlier this month found 45% of Brits had a positive view of Prince Harry, while 48 percent saw him in a negative light - giving him a net score of -3.

This is a significant drop of 15 points from the beginning of March, and marks the first time attitudes have been negative rather than positive towards the prince, it said.

The former Suit actress’s scores have also fallen considerably.

Just 31 percent of people have a positive opinion of her, while 58 percent view her negatively, YouGov found.

A source close to the Sussexes has since said that the public anger took them by surprise.

They added: “Harry and Meghan expected to face backlash, but nothing like this.”

Meanwhile, support for the other royals remained undimmed, it found.

The ever-popular Queen remained in rude health with 80 percent of people liking her.
