The Duke and Duchess of Sussex will formally step down as senior royals from 31 March, a spokesperson for the couple has said.
They will no longer carry out duties on behalf of the Queen but arrangements will be reviewed after 12 months.
Earlier this year Harry and Meghan announced they would be stepping back from royal duties and working to become financially independent.
They will return to the UK for engagements at the end of this month.
The couple intend to split their time between the UK and North America and the spokesperson said they would be in the UK “regularly” after stepping back from royal duties.
They will attend six events in the UK in February and March including the Commonwealth Day Service on 9 March.
Harry is also expected to attend the London Marathon in April in his capacity as Patron, while the couple will also attend the Invictus Games in the Netherlands in May.
As they will no longer be undertaking official engagements in support of the Queen, an office at Buckingham Palace will no longer be needed. From 1 April they will be represented through their UK foundation, the spokesperson said.
The couple will formally retain their HRH titles but will not use them. The spokesperson said the use of the word “Royal” is under discussion and an announcement will be made alongside the launch of their new non-profit organisation.
Harry and Meghan’s foundation applied to trademark the Sussex Royal brand – used on their website and social media – in June last year.
Harry will retain the ranks of Major, Lieutenant Commander, and Squadron Leader but his honorary military positions will be suspended. The roles will not be filled by anyone else during the 12-month review period.
