Close vote on G4S's takeover

The vote by shareholders of the security company G4S on its £5.2bn takeover of the Danish cleaning firm ISS is on a knife-edge. Two blue-chip investors, Artemis and Schroders, are expected to vote against the deal on Wednesday, according to reports over the weekend. The hedge fund Parvus Asset Management is also thought to be opposed to the takeover by G4S, which runs Birmingham prison and provides electronic tagging.
