Capturing listings of European technology companies is developing into a fight between London and New York. According to one London-based venture capitalist, at least 20 European tech companies are looking to list in London but regulation is said to be forcing firms across the Atlantic.

Robin Klein, a partner at London-based venture capitalist firm Index Ventures, and chairman of short-term loan firm Wonga, told Financial News: "From our own portfolio, and others we have looked at, we think there are at least 20 European firms that might want to list if the conditions were right. The London Stock Exchange is the natural place for these firms to list.
