Charles is the King of Colour as his first painting since becoming monarch goes on sale

The first painting of King Charles since he became monarch is now on sale at the Highgrove House shop.

The avid painter Charles’ watercolor of Mount Athos in Greece has been reproduced in 100 lithographs, which are now available for £2,950 each.

The king, who is estimated to have sold more than £2m worth of lithographs through the shop, modestly signed the painting ‘Charles 2022’, though shop staff tell me he autographed them after he ascended the throne.

Big congratulations to Seb Coe, who popped the question to PR powerhouse Sarah Robarts.

The couple, who are to marry later this year, were introduced by a mutual friend 18 months ago and fell “instantly in love”, according to the friends.

It will be a third marriage for the double Olympic gold medalist, 66, and a second for Sarah, 52, who counts Netflix and Amazon as clients at her women’s public relations firm Ballantines.

A friend says of the mother of two: ‘Sarah built her business from scratch. She is one of the best connected women in Los Angeles and a true powerhouse.

“She competes in triathlons, so while she’s not quite up there with Seb in terms of athletic achievement, they make a great team.”

Max closes the book

I may have written 80,000 words already, but Boris Johnson’s younger half-brother Max tells me he’s not going to publish his own memoirs until he’s on his deathbed.

Max, 36, who runs an investment advisory firm and lives in Hong Kong, seems unaware that his last name practically guarantees the success of the job, called FILTH.

He tells me: ‘I have come to the conclusion that there is no commercial interest in any of my lived experiences.’

Max also worries that his literary musings could burn bridges with family members and bore readers.
