Felipe VI and his wife Letizia will make their first visit to the UK since becoming king and queen of Spain last year. The royal couple have accepted an invitation from the Queen to pay a state visit in 2016, it was announced on Thursday.
The monarchs will visit from 8 to 10 March and will stay at Windsor Castle. The castle, which is a 90-minute drive away from London, is often used by Her Majesty as her weekend home.
It is also used for state banquets and in the past Windsor has hosted visits from King Abdullah II of Jordan and former leaders President Mbeki of South Africa and President Chirac of France.
