British Basketball's Performance Chairman, Roger Moreland, said:
"Chris has made a significant contribution to British Basketball and he moves to swimming with our thanks and best wishes. I know he will do a great job for one of the biggest sports in the Olympic Games and I appreciate what a fantastic challenge it is for him. British Swimming is very fortunate to have secured his services."
"This is a big opportunity for me and my experience working with basketball for the last six years has given me valuable insight into the organisation and structure required to improve sporting performance and I hope I can make a difference to British Swimming. I am very grateful for all the support I have received from everyone in basketball, from my colleagues and the players."
Last week, British Basketball succeeded in making a compelling case to UK Sport to have funding restored, which gives the Standard Life GB basketball teams the opportunity to continue their campaigns to qualify for the Rio Games. Moreland said:
"Personnel changes occur constantly in all organisations and the key is to use it as an opportunity to kick on to greater things. British Basketball will be no exception.
"We aspire to win medals consistently in international championships in the future and we are focussed on making that aspiration a reality. We know how important a performance focus is to UK Sport as well and we want to justify the faith they have had in our sport. Following last week's funding decision, we will be wasting no time in our pursuit of the very best Head Coaches to take the GB teams into their respective EuroBaskets this summer.
"We will also be looking at how we will replace Chris and will work closely with UK Sport to ensure we are as well positioned as we possibly can be to deal with the challenges ahead."
UK Sport's Performance Director, Simon Timson said:
"It is important to have a real focus on performance in any sport to achieve international success. British Basketball has moved from the backwaters of the international game to compete with the very best in the sport. Their task now is to win consistently in competition against the very best and we will work closely with British Basketball to support their efforts to maintain and enhance the focus they have on raising the level of performance through putting in place the best possible people to lead their drive for Rio."
