Rolls-Royce chief executive Warren East has said that his company is ready for a no-deal Brexit if it happens.
He told the Today programme that the firm was as prepared as it had been in March for the UK's departure from the EU.
And he added: "We’ve grown the amount of inventory that we have and other measures to deal with issues around Brexit, at a total cost of around £100m.
"We would obviously prefer a deal, because that is the best chance of providing certainty for business, but we’ve always been prepared for a no deal of some kind.
"We’re not a 'just in time business' and we are actually in a much stronger business than others.
"Most of our business is in aerospace and WTO rules apply anyway."
