King Felipe is preparing to for the Solemn Opening of the Courts, the opening of parliament, in the coming days.
Earlier this month His Majesty swore in Prime Minister Pedro Sánchez, who is leading a left-wing coalition government with Podemos.
The King last week swore-in other members of the incoming government at Zarzuela Palace.
Podemos leader Pablo Iglesias and Alberto Garzón wore pins to protest fascism. Both are considered anti-monarchists.
Sánchez’s Socialist Party is also nominally republican in nature but many of its members have come to appreciate the King’s role.
