MEDWAY, England - The leader of Britain's opposition Labour Party said Prime Minister Theresa May must move her red lines if there was any chance of a breakthrough on Brexit. 'The talks we are having with the government have been difficult,' Corbyn told reporters in Medway, southern England. 'There will be a further meeting coming up.' 'Quite honestly, the government has to move its red lines. We cannot go on having MV1, MV2, MV3 and then coming on for possibly MV4 or a bill we have yet to actually see.'
