Euronext, the European stock exchange, has stepped up its assault on the London market with a campaign to attract more international listings, particularly from Russia, Asia and former eastern European countries.

Euronext, which already has a number of foreign listings, has yet to rival the London Stock Exchange which dominates the market with 369 overseas stocks. The New York Stock Exchange and Nasdaq are the closest rivals to London in attracting international listings. Euronext's new marketing campaign will face competition from rival Deutsche Börse in one of its target markets, the former central and eastern European countries.
