The LSE's fall in its share of UK equity trades has outpaced declines at its European peers, vindicating new chief Xavier Rolet’s decision to enter talks with Turquoise.

The LSE executed 59.8% of all UK equity trades this month, compared with 62.4% in September, according to Thomson Reuters. Its market share has fallen from 73% in January and 96.1%, as recently as March 2008.
