That is surely nonsense.
firstly I thought it was far too unsafe for Harry to bring his family to the U.K. ever again?
secondly I can’t ever see Meghan allowing it.
thirdly it’s wildly wishful thinking on his behalf. You can’t just take two children who have been raised in California with no family or peer network in the UK and a completely different lifestyle and plonk them in a British boarding school and expect they’ll immediately form close knit bonds with a group of old school toffs.
It would be completely setting them up for failure.
The only credibility I can see with this is that it would align with the increasing hints we’re hearing that Harry wants reconciliation with the RF and that he wants his kids to have the chance to choose to be working members of the RF in future - maybe he thinks if he has them educated in the UK they could slot into that role more easily. But still, it’s nonsense. At the point his children are living in the UK for school it would be ridiculous for their parents to remain in California - Harry might be longing to come back to England but this is pie in the sky thinking if it’s come from him.
edited to add, the only way I could see this happening would be if they’d totally run out of money and this was the only way for Meghan to cling onto any sort aspirational lifestyle - by crawling back to the RF and hoping to be funded by Charles again (which I think he would do, if they agreed to live quietly and stop giving interviews, faux royalling and trashing the RF)
Harry would also need to get over his security issues and stop parroting the narrative that the UK is way too dangerous for him and his family.
