Major City institutions, including the London Stock Exchange, PwC and Standard Life Aberdeen, will travel to Saudi Arabia on Sunday, December 10 as part of a fresh push to tempt the country’s state-owned oil company to list in London.

The visit comes as the capital battles it out with New York, Hong Kong and Toronto to win over Saudi Aramco, which wants to float a 5% stake next year in what would be the biggest initial public offering ever.
