Lord Sainsbury returns to the Labour fold with £2m donation

The former chair of the supermarket chain was a big donor to Blair and Brown but cut off his support under Corbyn

Keir Starmer's election war chest has been given an extraordinary boost after one of the biggest New Labour-era donors returned to the party fold with a 2m donation, the Observer can reveal.

David Sainsbury, who was consistently one of the largest donors under the last Labour government before withdrawing his support, has now renewed his backing with his first multimillion-pound donation since 2016.
