LONDON: Prince Harry is facing mounting pressure to step aside for good as  around  25,000 people have signed a petition demanding the Duke of Sussex to give up all royal titles to 'stop damage to monarchy'.

Harry and Meghan stepped down as senior royals permanently earlier this year but still retain their titles.

Thousands of people have urged the Queen's grandson to stop "doing damage to the institution of the monarchy" by stepping aside for good.

Lady Colin Campbell, author of "Meghan and Harry: The Real Story" launched the petition as she thinks it's the right thing to do.

Colin told the Daily Star that Harry should request the Queen to put his royal style, titles and rank into abeyance.

The royal expert added: "It is the best solution because it frees Harry to be able to indulge himself without consequence and without doing damage to the institution of the monarchy of the British nation, the British people and himself." Prince Harry and his wife Meghan Markle would still be able to "sell their brand" without the royal titles, according to Lady Colin

Earlier in May, senior aides at Buckingham Palace also called on the Duke and Duchess of Sussex to give up titles after their tell-all interview with the US TV host.
