Boris Johnson has been given two weeks to explain his links to model-turned tech entrepreneur Jennifer Arcuri.

The London Assembly has asked the PM to provide "details and a timeline of all contact with Jennifer Arcuri including social, personal and professional during his period of office as Mayor of London".

The letter from Len Duvall, Chair of the London Assembly GLA Oversight Committee, gives Boris Johnson 14 days to address a potential conflict of interest with an entrepreneur.

The letter also calls for "an explanation of how that alleged personal relationship was disclosed and taken into account in any and all dealings with the GLA and other parts of the GLA family."

The oversight committee then has the legal power to summon Boris Johnson to give evidence in person if he fails to respond to the letter's request.

The Prime Minister refused to say whether he would support a full inquiry into the claims, despite an allegation of misuse of public funds.

Ms Arcuri, now 34, is said to have joined Mr Johnson on three trade missions when he was London mayor.

London’s City Hall and the Department for Culture, Media and Sport are examining allegations originally made in the Sunday Times.

One was that the organisation of London & Partners, for which Mr Johnson was then responsible, handed her firm £10,000 sponsorship money for an event in 2013.

Ms Arcuri said: “Any grants received by my companies and any trade mission I joined were purely in respect of my role as a legitimate businesswoman.”

Stopping short of directly addressing accusations relating to his relationship with Ms Arcuri, the prime minister told Sky News: "We did a huge amount of work while I was mayor of London selling our fantastic city around the world, beating the drum for London and the UK.

"I'm very proud of what we did. Everything was done with complete propriety and in the normal way."

Asked again to explain his relationship with Jennifer Arcuri, he said: "I can tell you that everything we did to promote London and the interests of London, London business, was done in a completely normal way and with utter propriety."
