A full-length portrait of a Spanish queen by Diego Velázquez is expected to smash the existing record for the celebrated and influential 17th-century artist when it is auctioned early next year.

Isabel de Borbón, Queen of Spain is valued in the region of $35m (£27.8m), more than double the current $16.9m auction record for a Velázquez.
