Despite suffering a setback from the collapse of its £21 billion merger with rival Deutsche Börse in March, the LSE delivers a 20% bump to the interim dividend to 14.4p.
Half-year profits swelled 20% to £398 million on an 18.1% rise in revenue to £853 million.
Driving the increase were strong figures from its clearing business, with the firm’s LCH unit seeing total income rising by a third thanks to a rise in interest rate swaps.
