The London Stock Exchange Group reported higher quarterly income as its clearing, capital markets and FTSE Russell businesses grew strongly.

The results helped ease lingering investor concern after a difficult 2017 for the company. 

Total income from continuing operations rose 13% to £520m in the quarter ended March 31, while total revenue was up 11% at £470m.

"The group has delivered a strong first quarter performance. All of our key businesses continue to perform well, with strong growth in FTSE Russell, LCH and Capital Markets," Interim chief executive David Warren said in a statement. 

The group named Goldman Sachs' veteran David Schwimmer as chief executive officer earlier this month, drawing a line under a management row between its chairman Donald Brydon and activist hedge fund TCI.

LSE's capital markets division, which makes money from fees paid by companies listing on its markets and trading of stocks and bonds, saw revenue rise by 14% to £107m. 

Revenue from information services rose 16% to £201m, with double-digit growth at FTSE Russell, LSE said, adding its income from its clearing business, LCH, surged by 18% in the first quarter. 

Schwimmer, who will take the helm in August, will have to protect LSE's strong hold in euro clearing as rival Deutsche Boerse in Frankfurt is already seeking to exploit Brexit uncertainty to build up business. 

LCH dominates euro swaps clearing.

In March last year, European Union regulators blocked the €29 billion merger between LSE and Deutsche Boerse, formally ending a deal that unravelled in the wake of the Brexit vote.
