They’re the small Canadian company credited with helping to take Britain out of the EU. Today Aggregate IQ boss Jeff Silvester appeared before Parliament to answer questions about the firm’s role in the controversial Vote Leave campaign. It comes after this programme broadcast allegations that Vote Leave may have broken election rules when they donated more than £600,000 to another campaign group, BeLeave. Mr Silvester said there was no co-ordination between the two campaigns. But the committee released new information provided by Facebook, which suggested that Vote Leave and BeLeave did share data files to target voters.
