LONDON (Reuters) - British aero-engine maker Rolls-Royce <RR.L> said it was continuing with contingency plans as uncertainty grows on whether Prime Minister Theresa May's Brexit plan will receive parliamentary backing, echoing comments from other firms.
"This agreement is only a draft," Chief Executive Warren East told BBC radio.
"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."
"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."
