The London Assembly will resume its investigation into Boris Johnson after the police watchdog ruled against undertaking a criminal investigation over his ties to US businesswoman Jennifer Arcuri while he was London mayor.
Ms Acruri, a technology entrepreneur, joined Mr Johnson on overseas trade missions in 2014 and 2015.
According to an investigation by the Sunday Times one of her businesses had received £11,500 in sponsorship money from a mayoral organisation when Mr Johnson was mayor and a £15,000 government grant for foreign entrepreneurs in Britain.
A further £100,000 grant was awarded to Ms Arcuri's company, Hacker House, by the Department for Culture, Media and Sport in January.
Mr Johnson is accused of not declaring a personal interest despite the pair having a friendship.
Len Duvall, the Greater London Authority's oversight committee chair, said: "The [Independent Office for Police Conduct] was looking specifically at whether he committed a criminal offence.
"That's not our remit and their decision doesn't have any real bearing on our investigation, which will focus on his conduct as Mayor of London.
"Our investigation will consider whether Boris Johnson conducted himself in a way that's expected from anyone in that position. It's important we get those answers, because Londoners deserve to have their politicians held accountable.
"The oversight committee will take into account the current emergency when looking at the timetable for the investigation."

Boris Johnson still has "questions to answer" over his relationship with US businesswoman Jennifer Arcuri, the Liberal Democrat candidate for mayor of London has said.
The Independent Office for Police Conduct said there was no case to answer after a nine month review.
It was alleged Ms Arcuri received favourable treatment during Mr Johnson's time as Mayor due to their friendship.
The investigation was sparked by a report in the Sunday Times that Ms Arcuri joined trade missions he led, and that she received thousands of pounds in sponsorship grants.
Siobhan Benita, Lib Dem candidate for Mayor of London, said: “It is outrageous that a decision as important as this comes so late, effectively kicked into the long grass during the general election.
"Boris Johnson may not be facing a criminal investigation but he still has many questions to answer.
"He should face the London Assembly so that his conduct can be thoroughly examined. Avoiding scrutiny may be his trademark but it should not be tolerated.”
US businesswoman Jennifer Arcuri says she is "upset" with how the prime minister has treated her.

Business woman Jennifer Arcuri says her answer would be "weaponised" against her and the prime minister.
