The British Olympic Association's announcement, after consultation with the Football Association, that the GB football team will consist of players from all four home nations has been met with outrage from the Scottish and Welsh Football Associations.

George Peat, the Scottish Football Association president, said of the BOA's "historic agreement": "I am absolutely astounded that they have put out this statement. I know nothing about any such agreement and we want nothing to do with this tournament."

The president of the Welsh FA, Phil Pritchard, was equally furious, saying the FA had no right to speak on behalf of the other associations on Olympic matters. Pritchard said: "We are not part of any agreement. The FA have no authority to speak on our behalf – they do not represent Wales whatsoever and that's a fact. We have not discussed this at any time recently."

Earlier the BOA had confirmed that footballers from Scotland, Wales, Northern Ireland and England will be available for selection for Team GB at the London 2012 Olympic Games.

A BOA statement said: "Consistent with requirements set out in the Olympic Charter, the selection criteria will be entirely non-discriminatory, as players from England, Scotland, Wales, Northern Ireland and other territories which fall under the BOA's remit, who meet the approved competitive standard, will be eligible for consideration and selection.

"The FA has consulted with its partner associations in Scotland, Wales and Northern Ireland in developing the player-selection criteria and timeline."

According to the BOA a longlist of players will be drawn up by the managers of the men's and women's teams and they will each be asked to confirm their availability. This will then be reduced to a shortlist and an announcement of the two squads will follow in the summer of 2012.

But the angry reaction from the Scottish and Welsh Football Associations to the BOA's announcement now puts this process in doubt.
