Vladimir Putin wanted Russia to join Nato but did not want his country to have to go through the usual application process and stand in line “with a lot of countries that don’t matter”, according to a former secretary general of the transatlantic alliance.

George Robertson, a former [UK] Labour defence secretary who led Nato between 1999 and 2003, said Putin made it clear at their first meeting that he wanted Russia to be part of western Europe. “They wanted to be part of that secure, stable prosperous west that Russia was out of at the time,” he said.

The Labour peer recalled an early meeting with Putin, who became Russian president in 2000. “Putin said: ‘When are you going to invite us to join Nato?’ And [Robertson] said: ‘Well, we don’t invite people to join Nato, they apply to join Nato.’ And he said: ‘Well, we’re not standing in line with a lot of countries that don’t matter.’”
