AEG, the US entertainment giant that owns the 20,000-seat arena, hopes to lure some of the classical world's biggest names. An O2 source said: "We are looking into holding a special programme at the start of next year, headed up with a major opera. The O2 is a vast venue and we are looking at ways to utilise it in a unique way for these events. It could be really spectacular and like nothing we have done before."
