Prince Harry is said to be reconsidering bringing his family to the UK after his request for police protection was reportedly turned down.
The Duke of Sussex was intending to travel with Meghan and their children, Archie and Lilibet, at the start of July.
It's been four years since the children last saw their grandfather in person and the King has offered to put the family up at an unnamed royal residence.
Harry is set to attend an event in Birmingham marking a year to go to the Invictus Games, the event he set up for injured military personnel, as well as visiting some charities he supports.
However, it's reported his request for taxpayer-funded police protection has recently been denied.
A source said the Duke of Sussex could now leave his family at home as he fears for their safety.
"[The duke] is looking at every option to try and get the family here safely and keep them safe when they're on the ground," the source told Sky News.
They added: "If he can find a way to do that he will. The hope is they can meet their grandfather, but there is no way that can happen if they are chased by paparazzi wherever they go from the moment they step off the plane.
"He won't put his children through that."
The duke last year lost a legal battle with the government over his level of security in the UK after it was downgraded when he stepped down as a working royal and moved to the US in 2020.
But at Harry's request, the Home Office body that decides on protection matters (Ravec) began reviewing his case.

Archie and Lilibet last saw the King at the late Queen's platinum jubilee celebrations in 2022 - and sources stress the monarch is not involved in decisions on his son's security.
A government spokesperson said: "The UK government's protective security system is rigorous and proportionate.
"It is our long-standing policy not to provide detailed information on those arrangements, as doing so could compromise their integrity and affect individuals' security."
