Reddish was first elected BPA chairman in 2008, taking over from Mike Brace.

The 59-year-old from Nottingham, who lost his sight in 1988 due to the hereditary degenerative condition retinitis pigmentosa, was then confirmed to continue as BPA chairman for another four years in 2013 having stood unopposed for the position.

A former elite disability swimmer, Reddish competed at three consecutive Paralympic Games - Barcelona 1992, Atlanta 1996 and Sydney 2000 - where he amassed three silver and two bronze medals.

The incoming chairman will be responsible for "leading the BPA Board and ensuring that it fulfils its responsibilities for the governance of BPA and to work in partnership with chief executive Tim Hollingsworth to help maintain the organisation's strategic direction".

The BPA is now looking to encourage nominations from a "broad cross section of potential candidates."

In addition to chairman, the BPA is also recruiting three members for the board of directors.

Reddish's work was recently recognised in the New Year’s Honours, as he was made a Commander of the Most Excellent Order of the British Empire (CBE).

"It has been a pleasure to chair the BPA over a significant period in its history and I am immensely proud of what has been achieved in this period," said Reddish.

"In the time I have been chairman there has been an unprecedented growth, exposure and excitement around the BPA, the Paralympic Games and movement and in turn its wider inspirational impact.

"I would encourage nominations for the new chair and three elected directors to be part of leading the BPA in what will undoubtedly be rewarding work in an exciting time for the organisation."
