Prince Harry and Meghan to arrive in UK today

Last year, Prince Harry lost a legal challenge over the levels of security he and his family are entitled to while in the country.

After the announcement of the Sussexes' intended return, a Home Office spokesperson said decisions on the security of royals were taken by the Executive Committee for the Protection of Royalty and Public Figures (Ravec), and the UK government's protective security system was "rigorous and proportionate".

It is unclear what provisions will be made for their security in the UK and who will pay for it.
