Donald Trump's shock victory shows that the Government must deal once and for all with the "overlooked" communities that have been transformed irrevocably by immigration without the "permission" of British voters, Theresa May will say.

In her first significant assessment of Mr Trump's election, the Prime Minister will say that his victory shows the need for a “new approach to managing the forces of globalisation” that does not ignore the working classes.

And she will launch a forthright attack on business figures who “appear to game the system” and “work to a different set of rules”.

In a thinly-veiled critic of figures including Sir Philip Green and Mike Ashley, the Prime Minister will warn that some company bosses are “undermining” the “reputation of business as a whole”.
