RPMI Railpen, the in-house manager for the UK's £25 billion Railways Pension Scheme, has named a new head of sustainable ownership - its third senior appointment in recent weeks.

Leo George, who has worked at Railpen for over eight years, will be tasked with integrating sustainable ownership considerations across the scheme's investments, RPMI Railpen said in a statement. He replaces Deborah Gilshan, who leaves at the end of March to join Standard Life Investments as governance and stewardship director.
