VLADIMIR PUTIN, Russia’s president, is sure to be cock-a-hoop on October 22nd when he poses for photographs with the leaders of perhaps 24 countries including Narendra Modi of India and Xi Jinping of China at the BRICS summit in Kazan on the Volga river. Last year, when the bloc met in Johannesburg and expanded from five to ten members, Mr Putin had to stay home to avoid being arrested on a warrant issued by the International Criminal Court in The Hague. This time he will hope to be seen playing a leading role in a rapidly growing club that is challenging the dominance of the Western-led order.
