London Stock Exchange shareholders have thrown their support behind the company’s potential acquisition of Refinitiv — a blockbuster deal that would create a UK data and trading behemoth and help the stock exchange draw a line under its failed merger with German rival Deutsche Börse.

The LSE’s share price surged by more than 15% on July 29 after it confirmed at the weekend it was in talks to buy US-based Refinitiv for $27bn.
