Boris Johnson used a keynote speech on Brexit, in which he tried to expose the “systematic campaign of subterfuge” with which European Union (EU) interference is hidden from the public and make the “liberal cosmopolitan” case for Leave, to launch a thinly-veiled attack on senior colleagues. Using the occasion of Europe Day — the officially EU-designated day to honour the former French Foreign Minister and leading architect of the European Project, Robert Schuman — Boris Johnson delivered what was trailed beforehand as his “biggest intervention” in the referendum campaign to date. Making what he described as the “liberal cosmopolitan” case for Brexit, the former London Mayor explained that the “anti-democratic absurdities of the EU” meant he had evolved into someone “deeply sceptical” about the EU. As such he said he was first “excited in 2013 by the Prime Minister’s Bloomberg speech” but afterwards “quietly despaired as no reform was forthcoming.” Quoting at length from David Cameron’s 2013 speech, which Mr. Johnson said “savaged the EU’s lack of competitiveness, its remoteness from the voters, its relentless movement in the wrong direction”, he pointed out that the Prime Minister’s much-vaunted renegotiation of the UK’s terms of EU membership amounted to nothing, and to claim otherwise is “an offence against the Trade Descriptions Act”.
