My friend and colleague Bob Morris, who has died aged 87, was the oldest among the many volunteers working for the Constitution Unit at University College London, which specialises in constitutional reform, with help from those with inside knowledge of government. He was also by far the longest serving, having worked with us for almost 30 years.
His time with the unit was almost as long as his time in the Home Office, where he was a senior civil servant for almost 40 years. He was highly respected and much loved in both roles, for his strong sense of public service, the breadth and depth of his knowledge, and his generosity in sharing it with others.
