"Recently, Cambridge Analytica has teamed up with Leave.EU – the UK’s largest group advocating for a British exit (or ‘Brexit’) from the European Union – to help them better understand and communicate with UK voters. We have already helped supercharge Leave.EU’s social media campaign by ensuring the right messages are getting to the right voters online, and the campaign’s Facebook page is growing in support to the tune of about 3,000 people per day."

Strange how they now deny any involvement.
