John McFarlane will replace Lord Sharman of Redlynch as Aviva's chairman at the end of June 2012.

McFarlane, currently a resident of Australia, will become a non-executive director of Aviva on 1 September this year and will be named deputy chairman on 1 January 2012.

McFarlane is a non-executive director of Royal Bank of Scotland Group plc and Westfield Holdings Limited and was for 10 years chief executive officer of Australia and New Zealand Banking Group Limited (ANZ). Among other senior positions, he was also group executive director at Standard Chartered, head of Citibank in the UK and Ireland, a non-executive director of the London Stock Exchange and a member of the Auditing Practices Board and The Securities Association (UK securities regulator).

He will step down from the board of the Royal Bank of Scotland by 31 March 2012 and will relocate from Australia to the UK for the purpose of carrying out his duties as chairman of Aviva.

“John McFarlane’s extensive experience as both an executive and non-executive director in international financial services will be invaluable to Aviva," Lord Sharman said in a statement.

McFarlande added: “I am delighted to be joining Aviva in such an important role. Aviva is a great company and an excellent brand and recent results show that the hard work over the last few years is paying off."
