Trading on the London Stock Exchange's electronic order book surged more than two-thirds to a record last month following investments in new technology and a boost to the system's capacity.

The value of trades on Sets, the LSE's electronic order book, soared 69% to £141bn (€202bn) in March, while the number of trades reached an all-time high of 6.7 million, 53% more than recorded in March last year.
