British aero-engine maker Rolls-Royce said it was continuing with contingency plans as uncertainty grows on whether Prime Minister Theresa May's Brexit plan will receive parliamentary backing.
The company's comments echoed statements from other firms.
"This agreement is only a draft," the company's chief executive Warren East said.
"There are a lot of steps to go between here and when we are done and we can't guarantee anything out of this but I do have to be able to guarantee that we can continue doing our business after the 29th of March next year," the CEO stated.
"We are going to continue with our contingency plans and that includes buffer stocks so that we have all the logistical capacity that we need to carry on running our business," he added.
