A former Labour science minister, David Sainsbury, 76, spent more money than anyone trying to keep Britain in the EU but his £4.2m failed to buy him the result he was hoping for. He also stumped up £2.1m each to Labour and the Liberal Democrats, although at one stage there was talk of him getting suspended from Jeremy's Corbyn's party for his Lib Dem gift. The supermarket chain that created the peer's family fortune had a better year and is now valued at £5.85bn. Sainsbury has given away more than £1bn through his London-based Gatsby Charitable Foundation, while other family members have also donated about £300m.
