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

King Charles’s first painting since becoming monarch is now on sale at the Highgrove House shop.

Avid painter Charles’s watercolour of Mount Athos in Greece has been reproduced into 100 lithographs, which are now up for grabs for £2,950 each.

The King, who is estimated to have sold more than £2 million of lithographs through the shop, modestly signed the painting ‘Charles 2022’ – although shop staff tell me he autographed them after ascending to the throne.

Lord Sebastian Coe and his new fiancee Sarah Robarts in Monaco

Many congrats to Seb Coe, who has popped the question to PR powerhouse Sarah Robarts.

The couple, who will marry later this year, were introduced by a mutual friend 18 months ago and were ‘instantly smitten’, according to chums.

It will be a third marriage for the double Olympic gold winner, 66, and a second for Sarah, 52, who counts Netflix and Amazon as clients at her all-female PR firm Ballantines.

A friend says of the mother of two: ‘Sarah built her company from scratch. She’s one of the most well-connected women in LA and a real powerhouse.

‘She competes in triathlons, so while she is not quite in Seb’s league in terms of athletic accomplishments, they make a great team.’

Max closes the book

Max Johnson, Boris Johnson’s younger half-brother

He may have already written 80,000 words but Boris Johnson’s younger half-brother Max tells me he isn’t going to unleash his own memoir until he’s on his deathbed.

Max, 36, who runs an investment advisory firm and lives in Hong Kong, seems unaware that his family name pretty much guarantees the success of the work, called FILTH.

He tells me: ‘I’ve concluded there is no commercial interest in any of my lived experiences.’

Max is also concerned that his literary musings might burn bridges with his relatives and bore readers.
