Hans Holbein the Younger, during his London visit, completes his portrait of Sir Brian Tuke in 1528 before returning to Basel.
The earliest mention of Master of the Posts is in the King's Book of Payments where a payment of one hundred pounds in February 1512 was authorized for Tuke as master of the posts.
Belatedly, in 1517, he was officially appointed to the office of Governor of the King's Posts, a precursor to the office of Postmaster General of the United Kingdom, by Henry VIII.
He was made a knight of the king's body in 1516, and in 1517 governor of the king's posts.
Tuke was for some time secretary to Cardinal Wolsey, and in 1522 he was promoted to be French secretary to the king; much correspondence passed through his hands, and there are more than six hundred references to him in the fourth volume alone of Brewer's Letters and Papers of Henry VIII.
Tuke on April 17, 1523, was granted the clerkship of parliament surrendered by John Taylor.
He is one of the commissioners appointed in 1528 to treat for peace with France, and in the same year is made treasurer of the household.
