A senior Conservative Eurosceptic has reportedly warned businesses that they will pay a "very dear economic and financial price" if they speak out in favour of Britain staying in the European Union.
According to the Telegraph, former minister John Redwood told a fringe event at the Conservative Party Conference that firms should "keep out" of the debate and "not meddle in politics".
The newspaper quotes Redwood as saying: "If they don't understand that now they will find those of us organising the 'get out' campaign will then make life difficult for them by making sure that their customers, their employees and their shareholders who disagree with them - and there will be a lot who disagree with them - will be expressing their views very forcefully and will be destablising their corporate governance."
