Input: Consider Input: Question: How old was the Liberal Unionist MP when he died? Passage:Morton first stood for Parliament at the 1885 general election, when he contested Hythe, and was unsuccessful again in Christchurch at the 1886 election. He won a seat three years later, when he was elected at a by-election in October 1889 as the Member of Parliament (MP) for Peterborough, after the death of the Liberal Unionist MP John Wentworth-FitzWilliam, becoming the 81st new MP since the general election in 1886. His victory was unexpected, and when the result was declared he said that he hoped his victory would be seen as a gesture of conciliation Ireland. He was re-elected in 1892, and raised in Parliament the issue of the appointment of Justices of the Peace (magistrates) in April 1893. In November that year, 280 Gladstonian MPs met the Lord Chancellor, Lord Herschell, in the House of Lords to discuss the system. Morton led the response to the Lord Chancellor's explanation and defence of the existing system of appointment, and denounced the reliance on advice from Lord Lieutenants who were entirely dependent on what Morton called "class cliques". He was also a member of a Select Committee set up to examine the accommodation provided for members and officials of the House of Commons. Great Western Railway
