Quentin Fitzsimmons will leave his position as government bonds chief at UK-based Threadneedle Investments in July, the firm has confirmed.

Fitzsimmons has been with the company since 2003 and led its absolute return bond strategies. The next destination in his career is not known at this stage.

Matthew Cobon, fund manager and foreign exchange specialist, is currently co-manager of the Threadneedle Absolute Return Bond and Target Return funds and will assume lead responsibility for them.

Other funds managed by Fitzsimmons will be taken over by the other members of the fixed income team including Richard Stevens, Dave Chappell, Martin Harvey and Matt Rees.

The firm said in a statement that it is currently making changes to its fixed income platform and that it will shortly announce appointments in the space.
