Commenting on allegations that Cambridge Analytica misled Parliament Liberal Democrat Spokesperson on Brexit Tom Brake, said:
 “The allegations coming out about Cambridge Analytica are deeply concerning.
 “If MPs were lied to, or misled, then those involved must be held to account in parliament.
 “The Brexiteers tell us this is the biggest vote in British history, the public now deserves answers to these emerging questions about whether the campaign was conducted in a fair way.”
