Purvis was married with three children and ten grandchildren. He had farming and property interests in North East Fife and had extensive knowledge of the international financial services industry, having worked in the sector for several decades and having later contributed his expertise on relevant committees in the European Parliament.
In his first term he was appointed to the new Internal Market subcommittee of the Economic and Monetary Affairs Committee.[3] In this capacity he worked with fellow UK MEP Basil de Ferranti and others to propose harmonised standards across a wide range of goods. Their final proposals would form the basis of the Single European Act in 1985.[3]
During his second term as an MEP, Purvis was elected Vice Chairman of the European Parliament's Economic and Monetary Affairs Committee in 2002, and then re-elected to this position during his third term in 2005 and 2007 (2002–2009). He was also a member of the Committee on Industry, Research and Energy[2] (1999–2009). He also served on EU delegations to the Gulf States and to Middle Eastern countries and served on the EU Committee of Inquiry into the Equitable Life Assurance Society crisis. During his 15 years as an MEP, Purvis produced a number of major reports which helped to shape EU policy – notably on biotechnology (supporting GM foods),[4] telecommunications and financial regulation.[5][6]
In 2001, Purvis spoke out against the legality of actions by Customs and Excise officers who were confiscating alcohol and tobacco bought for personal use from travellers returning from the European Union saying such actions were illegal.[7][8]
In 2002, Purvis stated that he supported the building of a new airport in central Scotland as an alternative to upgrading the airports at Edinburgh or Glasgow.[9]
In 2008, it was alleged that Purvis may have breached rules regarding parliamentary expenses and the payment of staff through a company. Purvis said at the time that he sought clarification from the relevant authorities and such clarification was not forthcoming.[10][11] He was cleared of any wrongdoing.[12]
Since standing down in 2009, Purvis continued to serve in Europe as Chairman of Financial Future Forum[13] which provides a means of dialogue between the financial services industries of Europe and the EU's legislators. He was also Chairman of Belgrave Capital Management in London,[14] and was for many years a Director of Kingdom FM Radio Ltd., Fife,[15][16] and Advisor to the Board of Elmwood College in Cupar (2012).
He died following a battle with cancer on 20 March 2022, at the age of 83.[17]
