September 30: Mr Johnson insists allegations over his private life, including his links to Ms Arcuri and the allegation he squeezed the thigh of a female journalist, will not overshadow the Tory Party conference.
October 1: The Prime Minister tells LBC radio that allegations over his personal life had only come out because of some people’s intent to ‘frustrate’ Brexit.
October 3: Ms Arcuri tells the Daily Mail she had ‘every right’ to go on trade missions with Mr Johnson. She calls all the allegations false, saying she is a ‘legitimate businesswoman’.
October 6: The Sunday Times reports that leaked emails showed that Ms Arcuri had listed Mr Johnson as a reference in her application for a role in Tech City.
