The G8 +5 group was formed in 2005 when Tony Blair , then Prime Minister of the United Kingdom , in his role as host of the 31st G8 summit at Gleneagles , Scotland , invited the leading emerging countries to join the talks . The hope was that this would form a stronger and more representative group that would inject fresh impetus into the trade talks at Doha , and the need to achieve a deeper cooperation on climate change
