This has been a record year for world stock markets with IPOs raising £116 billion ($227bn), according to Ernst & Young.

The Hong Kong Stock Exchange did best, grabbing 17pc of the total. But the London Stock Exchange came a close second, with 15pc, ahead of the New York exchange on 11pc, Euronext on 8pc, and Nasdaq, at a lowly 6pc.

Much of the bonanza has come from Russian and Chinese companies seeking havens in lightly-regulated financial centres. The LSE has scored heavily over the American outfits because of the negative effect of the Sarbanes-Oxley legislation.
