Montagu had a long and active career as a Court supporter under Charles II, and had acted as a judge at the trial of Lord Russell (William†) after the Rye House Plot. He was returned unopposed for Amersham at a by-election in 1690 on the Drake interest, then in the hands of his daughter, the widow of the recently deceased Sir William Drake*. The only legislative matter mentioned in the Journals which can definitely be attributed to ‘Mr Serjeant’ Montagu was a bill for the more easy recovery of small tithes, which, on 11 Oct. 1690, he and others were ordered to prepare. In December 1690, the Marquess of Carmarthen (Sir Thomas Osborne†) included his name among a list of supporters, probably in connexion with an attack in the Commons upon his ministerial position. His name is marked with a ‘d’ on Robert Harley’s* list of April 1691. On 18 Jan. 1692 he spoke in committee of the whole on supply in favour of a tax on the profits of office over £500 p.a. which had been suggested by Admiral Russell (Edward*) on 12 Dec.3 Luttrell Diary, 136.
Montagu never stood again, and died on 26 or 27 Aug. 1706. The major beneficiary of his will was his daughter, Lady Drake, who had subsequently married Samuel Trotman*, although some of its provisions gave rise to legal suits which reached the House of Lords.4 Le Neve, Mon.
