They kicked off their UK visit with an action-packed first day that saw them darting between Buckingham Palace, Clarence House and Parliament, topped off with a glittering banquet.

And the Spanish royals continued their tour on Thursday as they joined Prince Harry on a visit to Westminster Abbey - marking the 32-year-old's first official role in a state visit.

King Felipe VI and Queen Letizia laid a wreath at the Grave of the Unknown Warrior today while prayers were said by the Dean John Hall, before being taken on a short tour which was live-streamed on the Abbey's Facebook page.

Flanked by clergymen, Letizia, who stunned in a show-stopping red gown at last night's banquet, wore a more pared-back ensemble today consisting of a blue silk blouse and embroidered A-line skirt from Carolina Herrera.

During their visit today they also viewed the tomb of Eleanor of Castile, the Spanish princess who married England's Edward I in the thirteenth century and a distant ancestor of the Felipe, 49.

The King had an early start this morning, attending a UK-Spain business forum at Mansion House with the Duke of York, and later he meet Theresa May at No. 10 Downing Street along with his wife.

This week's visit is seen as an important step in securing relations with Spain as the UK leaves the EU; the last incoming state visit by a Spanish king - Felipe's father Juan Carlos I - was 31 years ago in 1986.

King Felipe VI and Queen Letizia's trip had been postponed twice - firstly because of a political crisis in Spain in March 2016, and then again when the rescheduled date clashed with June's snap general election.

Yesterday, the couple were formally greeted by the Queen and the Duke of Edinburgh on Horse Guards Parade, marking the beginning of Philip's last state visit before he retires from public duties in the autumn.

The couple - parents to 11-year-old Leonor, Princess of Asturias and 10-year-old Infanta Sofía of Spain - then enjoyed a private lunch with the royal family at Buckingham Palace.

During the lunchtime reception, Felipe VI became what is known as a 'Stranger Knight' or 'Extra Knight Companion' of the prestigious Order of the Garter.
