A key member of the London Stock Exchange’s executive team sold more than £1m of shares in the group, after the rise of the stock price since the group struck a deal to acquire data company Refinitiv for $27bn.

Daniel Maguire, the chief executive of LCH, a group of clearing houses, sold 14,706 shares in the LSE, according to a regulatory filing. His remaining shareholding is unclear. He sold the shares at a price of £68.315 each. The LSE declined to comment on the sale of the shares.
