Thomson ReutersPARIS (Reuters) - Airbus issued its strongest warning yet over the impact of Britain's departure from the European Union, saying a separation without a final deal between Britain and the EU would force it to reconsider its long-term position in the country. In a statement issued late on Thursday, Airbus also said current plans for a transition period ending in December 2020 were too short for the planemaker to adapt its supply chain and would mean no further expansion in its UK supplier base.
