M&G Securities' chief executive and chair William Nott has left the company to join SYZ Asset Management.
He will take on the role of chief executive at SYZ from 7 January 2019. He will become a member of the executive committee and a key shareholder of the business.
Under Nott's leadership, M&G has grown from a £11.7 billion in client funds to £80.1 billion.
SYZ group CEO Eric Syz (pictured), commented: 'The SYZ Group is immensely pleased to have a proven leader like William Nott join the organisation.
'His track record in business development, asset management, corporate governance and strategic leadership make him a great match for the SYZ Asset Management position and a fantastic addition to the group.'
Nott joined M&G as a graduate from Warwick University in 1984. He was appointed CEO of the firm's retail business in 2006.
Last year he was elected to serve as president of the European Fund and Asset Management Association for a two-year term.
Nott added: 'I am delighted to be joining the SYZ Group at such an exciting time in its evolution and development. Eric Syz has been a pioneer in his field and I am very excited to be working with him leading the next phase of delivering excellent investment outcomes for our clients.'
