The House has just lost one of its oldest, but also one of its most active, members in Lord Walton of Detchant, who has died at the age of 93. He was a regular attender and speaker until a few weeks ago, when he was taken ill. He was professor of neurology at Newcastle University for many years and variously served as President of the British Medical Association and of the General Medical Council, among other bodies. Though retired, he kept up his contacts in the medical world and contributed authoritatively on medical issues in the House. He carried weight because of his knowledge and authority in the field. He neither looked or acted like someone in their nineties. He would drive regularly to the station at Berwick upon Tweed to catch the train to London. Until taken ill, he was notably fit – he looked at least twenty years younger than he was – and his only apparent infirmity was a growing deafness, though it was not perhaps as bad as he thought. I saw him regularly as a fellow lunchtime diner in the Bishop’s Bar. He held eleven honorary degrees, including one from Hull, so he would frequently ask how the university was doing. Among some of his recent contributions were those on whiplash, adult pneumococcal vaccination, and the Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015, which illustrate the value of having such expertise in the House. He was greatly respected across the House and will be much missed.
