The Norwich South MP and Labour leadership contender Clive Lewis has suggested the Duchess of Sussex had been the victim of "structural racism" in the media.
Speaking to Sky News he said "We can see it with Meghan Markle and the way that she's been treated in the media. We know this is a reality of the 21st century still after 400 years of racism."
It comes as the Queen was seen in public today, arriving by car at church in Sandringham dressed in a camel coloured coat and hat.
She is due to host crisis talks with senior royals and the Duke of Sussex at Sandringham on Monday in a bid to find a solution to Meghan and Harry's future roles.
The head of state will be joined at her private Norfolk estate by the Prince of Wales and Duke of Cambridge for the crunch meeting - where the"next steps" will be decided.
It will be the first time the four will have met since the issue engulfed the royal family.
Clive Lewis currently has just four nominations from MPs and MEPs - 18 short of the total he needs to secure by 2.30pm on Monday if he is to make it through to the next stage of the contest.
He has not shied away from taking controversial stands, describing himself as a republican and calling for a referendum on the future monarchy.
