The £1.3bn infrastructure fund run by construction group John Laing, which owns assets from the Ministry of Defence’s HQ to the Docklands Light Railway, is set to be sold after a crunch vote of shareholders went five-to-one for the deal.

The acquisition, by infrastructure fund managers Dalmore Capital and Equitix, was approved by 86% of the listed fund’s shareholders who voted, the company said in a statement late on September 24.
