The signing of the contract took place in Rio de Janeiro, coinciding with the Paralympic Games taking place in the Brazilian city.

Allen was joined by World ParaVolley President Barry Couzner at the signing ceremony, which also took place in front of several of the governing body’s board members.

"On behalf of World ParaVolley I am pleased to announce that Mr Phil Allen has been re-appointed as general manager for the next four years," Couzner said.

“Mr Allen has brought a high degree of professionalism in the finances and administration of the organisation over the past few years.

"We look forward to his continued commitment to World ParaVolley that will ensure a high level of service for our membership."

The contract will see Allen remain in the post in the build-up to and throughout the Tokyo 2020 Paralympic Games.

The men’s sitting volleyball competition at Rio 2016 saw Iran avenge their defeat in the London 2012 final, as they beat defending champions Bosnia and Herzegovina to win gold.

Gold was claimed in the women’s event by the United States, as they overcame China 3-0 in the final.

World ParaVolley also govern standing volleyball, but the discipline is not part of the Paralympic Games sport programme.

Sitting and standing beach volleyball disciplines are also governed by World ParaVolley.
