Webster was a prominent figure in the reform movement in Sussex. On 18 Jan. 1783, at a meeting at Lewes, he introduced a petition for parliamentary reform, with what Wyvill called ‘a very pertinent and judicious exordium’. But on 24 May 1785, at a meeting at the Thatched House Tavern, he opposed Pitt’s parliamentary reform proposals as inadequate.
Webster made no mark in the House, and apparently never spoke during his first Parliament. He adhered to the Opposition, voting with them on the impeachment of Sir Elijah Impey and the Regency. His harsh and overbearing character found few apologists. A notorious rake and spendthrift, one of the most reckless gamblers of his day, he had a violent and ill-controlled temper and seemed at times on the verge of insanity. The story of his unhappy marriage is well known from the journal of his wife, afterwards Lady Holland.
