AceShowbiz - Meghan Markle, Duchess of Sussex's father has sent "all the good wishes in the world" to King Charles. The 75-year-old monarch was diagnosed with an undisclosed form of the disease after a "separate issue of concern" was detected when he underwent a procedure for an enlarged prostate last month, Buckingham Palace announced on Monday, February 5 and now Thomas Markle - who is estranged from his daughter and didn't attend her 2018 wedding to Prince Harry - has sent a message of support to the king.

"I want to send my best wishes to King Charles and hope he gets well very soon. I wish him all the good wishes in the world," he told MailOnline.

Charles' cancer diagnosis was announced in a statement by Buckingham Palace. The statement read, "During The King's recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted. Subsequent diagnostic tests have identified a form of cancer."

"His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties. Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual."

"The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure. He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible."

"His Majesty has chosen to share his diagnosis to prevent speculation and in the hope it may assist public understanding for all those around the world who are affected by cancer."

The king's son Harry is to return to the UK from his California home to spend time with his father, but his wife Meghan and their children, Prince Archie, four, and two-year-old Princess Lilibet are not expected to travel.
