In April 1640, Glynne was elected Member of Parliament for Westminster in the Short Parliament. He was re-elected MP for Westminster for the Long Parliament in November 1640. His first major parliamentary triumph was the summing-up of the case against the Earl of Strafford, and he enjoyed a successful career during the commonwealth, becoming a serjeant-at-law, judge of assize, and finally Lord Chief Justice of the Upper Bench, and was a member of the Committee of Both Kingdoms. However, his Presbyterianism put him out of favour of with the army, and he was expelled from Parliament in 1647 and imprisoned in the Tower for almost a year. He was counsel for the University of Cambridge from 1647 to 1660. He returned to Parliament for Caernarvonshire from 1654 to 1655 in the First Protectorate Parliament. In 1656 he was elected MP for both Carnarvonshire and Flintshire in the Second Protectorate Parliament and chose to sit for Flintshire. He was nominated and accepted a seat in Cromwell's Other House. In 1656 he was judge in a criminal case involving George Fox. After several allegations against Fox failed to stand up, he demanded Fox remove his hat, and on his refusal to do so, ordered him to pay a fine of 20 marks and committed him to prison until he did so. In the later years of the Protectorate, Glynne resigned his legal offices and turned to favour the Restoration. He was returned again for Caernarvonshire in the Convention Parliament, and was knighted on 16 November 1660, and shortly thereafter made Prime Serjeant.
