Co-chairman of the Income Protection Task Force (IPTF) Clive Waller is to step down from his role at the end of this year.
Peter Le Beau, with whom he currently shares the chair, will become the sole chairman of the organisation.
Waller, who helped set up the IPTF in 2007, also runs a research-based consultancy, CWC Research, with his wife, Monica.
He explained he would be likely to remain on the non-executive board but in a 'hands off' capacity.
He added: "Since the IPTF was formed, my business has become increasingly investment-focused and I no longer have the close contact I used to have with the income protection market.
"The IPTF requires a chairman who works in this market on a day-to-day basis. For this reason, I feel it is sensible to let Peter Le Beau assume the chairmanship although I remain deeply committed to the goals and objectives of the Task Force.
I am very proud of the spotlight we have been able to throw on what is still a sadly unsold product."
Peter Le Beau said: "Clive has done a monumental job during his time on the Task Force and has been a very wise counsel to me over the last eight years.
"He has a great passion for the product and a deep sense of treating consumers properly, which has been of immense value to the Task Force since it was formed. I hope he will be able to stay as part of the Executive going forward."
