[1] He is not recorded as playing any part in the English Civil War, but following the Stuart Restoration in 1660, Broke was appointed one of Suffolk's militia commissioners and a justice of the peace for the county.
He was active in local affairs in Suffolk, and in 1681 he presented a loyal address to Charles II from the people of Ipswich.
The King, having had long experience of his "fidelity and zeal in his service", commissioned Broke to report on infractions of the charters and of the Corporation Act 1661 in Ipswich.
A moderately active Member, he was appointed to the committee of elections and privileges and that to consider the bill to prevent the export of wool.
In April 1688, James II's agents in Suffolk reported that Broke was loyal to the king, but he was removed from municipal office in July and did not stand at the following general election; he took no further part in public life.
