Axa Investment Managers has lost its second senior executive in a month with the departure of UK business head Irshaad Ahmad.

Ahmad, a Canadian who joined the €694 billion manager in June 2011, left the firm on October 16 after he decided to pursue "a new opportunity", Axa IM confirmed in a statement on October 21. His departure comes less than a fortnight after the exit of its global head of smart beta credit Bill Healey, a fixed income and credit market veteran.
