The decision was made on Tuesday and understood to have been backed by Queen Consort Camilla and the Prince and Princess of Wales.
But there seems to be a sense of dismay amongst other royals including Prince Andrew and his daughters Princesses Eugenie and Beatrice.
As per a report, the Sussexes were apparently informed just 24 hours after the release of the memoir. Sources close to the couple have described the decision as 'a cruel punishment.'
As of now, the Sussexes do not have access to any other Royal residences and do not own another home in the UK, therefore meaning that this eviction ensures they are now fully committed to living in the US.
