Bromley was held in favour by Henry VIII, who made him one of the executors of his will, and bequeathed him a legacy of £300. Hence he was one of the council of regency to Edward VI and a Privy Counsellor; but, although he succeeded in avoiding political entanglements for some time, at the close of the reign he became implicated in Northumberland's scheme for the succession of Lady Jane Grey. The duke summoned to court Montagu, chief justice of the common pleas, Bromley, Sir John Baker, and the attorney- and solicitor-general, and informed them of the king's desire to settle the crown on Lady Jane. They replied that it would be illegal, and prayed an adjournment, and next day expressed an opinion that all parties to such a settlement would be guilty of high treason. Northumberland's violence then became so great that both Bromley and Montagu were in bodily fear; and two days later, when a similar scene took place, and the king ordered them on their allegiance to despatch the matter, they consented to settle the deed, receiving an express commission under the great seal to do so and a general pardon. Bromley, however, adroitly avoided witnessing the deed.
