Diego Sarmiento de Acuña, 1st Count of Gondomar

Diego Sarmiento de Acuña, 1st Count of Gondomar (November 1, 1567 – October 2, 1626), referred to simply as Count Gondomar, was a Spanish nobleman and diplomat. He twice served as Spain's ambassador to England and later held an informal but influential role as Spain's leading expert on English affairs, a position he maintained until his death.

In England, Gondomar was widely regarded as the leader of a Spanish faction at the English court, a confidant privy to the inner thoughts of King James I, and working to advance the Papist cause. Provided by Wikipedia
