They are the third country to choose Stoke Mandeville, where the seeds of the Paralympics were sown in 1948 when Sir Ludwig Guttman organised events for World War Two veterans with spinal cord injuries who were rehabilitating at the local hospital.

Finland and Uganda have already signed deals to train there before London 2012.

They have now been joined by Papua New Guinea Paralympic Committee (PNGPC), who signed a Memorandum of Understanding (MoU) to use Stoke Mandeville after visiting a number of facilities, including Medway Park, Canterbury High School, Sevenoaks School and Guildford Spectrum Leisure Complex.

Dr Kefu Ma, the Chef de Mission of the PNGPC, settled on Stoke Mandeville because he believes that it offers the best facilities for the sprinters and powerlifters expected to make up the bulk of Papua New Guinea's team at London 2012.

For the Paralympics in Beijing in 2008, Francis Kompaon won Papua New Guinea's first-ever medal in the Paralympics, finishing second in the T46 100 metres.

Ma said: "I have very much enjoyed visiting the South East area and had been really looking forward to coming to Stoke Mandeville which is known throughout the world as the birthplace of the Paralympics.

"I have been very impressed with the quality of sporting facilities and have enjoyed a very warm welcome throughout my visit.

"I am particularly pleased that I was able to come here to the spiritual home of the Paralympics."

Ian Barham, the Buckinghamshire manager for the 2012 Games, and Ian Seabrook, the business development manager for Stoke Mandeville Stadium welcomed Dr Ma to Stoke Mandeville and were delighted at his decision to choose this area as a base for his athletes.

Barham said: "We are both looking forward to welcoming athletes to our area from nations both large and small over the next three years.

"The presence of international athletes in our area offers great scope for educational, economic and cultural links to be developed with visiting nations which will definitely generate huge interest as we prepare for 2012.

"The name of Stoke Mandeville is famous throughout the world and a real attraction for international athletes."

Seabrook said: "It is an honour that Dr Ma has selected Stoke Mandeville Stadium as the pre-2012 Games training venue, and it shows that the reputation and the name of the centre is recognised around the world."
