Meghan, Duchess of Sussex has personally phoned a British MP to thank her for penning an open letter of solidarity with the under-fire royal.

On Tuesday Halifax MP Holly Lynch, along with 71 other female MPs from all corners of British politics, sent the Duchess a letter to support her stand against “distasteful and misleading” coverage of her and her family in the tabloid press.

The letter said the “stories and headlines have represented an invasion of your privacy and have sought to cast aspersions about your character without any good reason as far as we can see”, and alluded to racist “colonial” undertones in some of the coverage.

“As women members of parliament from all backgrounds, we stand with you in saying it cannot be allowed to go unchallenged,” the letter read.

The letter clearly hit a chord with the Duchess, as she phoned Ms Lynch on Wednesday (British time) to thank her.

“I got a phone call – it was Buckingham Palace asking me was I available to speak to the Duchess of Sussex,” Ms Lynch told ITV News.

“She was calling to thank myself and other women MPs for standing with her and sending the open letter to say we as women in public office absolutely understand what she is going through, although in very different public roles.

“We stand with her in solidarity to say that we shouldn’t be tearing down women in public life through the press or otherwise.

“She was pleased to have seen that letter.”

The letter came after the Duchess admitted the intense media scrutiny she felt during her pregnancy and as a new mother had been “really challenging”.

Last month Meghan and her husband Prince Harry launched legal action against the Mail on Sunday newspaper for a breach of privacy after it published a handwritten letter sent to her father, Thomas Markle, shortly after the couple married in May 2018.

The Mail on Sunday has denied the accusation and said it would defend the case “vigorously”.
