Well, given that Meghan is at least three months pregnant, probably four, and the Sussexes will need an at least decent sized London residence of some sort in future years, a decision will have to be made by somebody soon.
Meghan has no convenient Bucklebury to take her baby to, Nott Cott is miles too small for the couple, plus nanny and baby, and so...? Do they go off to a rented property in the Cotswolds for several months, then?
Considering every one of the Queen's children has one property not bought by themselves, plus William has too, are Harry and Meghan just going to be left to their own devices, with the dismissive tone in that article 'Oh they have their own money, they can buy elsewhere in London' prevailing? Apparently Harry is to be treated differently to everyone else.
Plus, the report at the term of William and Kate's wedding that the Gloucesters were oh so willing to move out of their apartment in favour of the Cambridges was a bunch of lies apparently. Either that or the Press has decided to push 'The Sussexes want to throw a hardworking couple out of their old home' line!
Well actually if he were left to pay for his own residence he would be being treated the same as all the Queen's other grandchildren (Zara, Peter, Eugenie) It may well be William is the one being treated but he is a direct heir.
I don't believe for one minute the Gloucester's would refuse to move out, it would not surprise me at all if the whole story came from Princess Michael's blatant attempts to push it for her own agenda and having run with it the press are clinging to anything that explains why H&M aren't moving into Apartment 1.
