Jeremy Corbyn wants companies that profit from replacing humans with robots to pay more tax because he believes automation is a “threat” to workers.

The Labour leader wants to use the money to create a fund to retrain staff who lose their jobs because of new technology. He said that “we should all get the benefits” from “greedy” global corporations such as Amazon which have “made a great deal of money out of incredibly advanced technology”.

In his speech to the Labour conference on Wednesday, he will set out plans to “manage” robotics and technology “for the benefit of society as a whole”.
