Brussels officials have reportedly suggested that the UK might have spied on them. The allegation refers to a slideshow presented to them in July, just before the Chequers summit, in which a European Commission economic assessment that was critical of Theresa May's Chequers plan was delivered. Very shortly afterwards, the British government is said to have lobbied to block publication of the slides.
