The London Assembly's Oversight Committee, chaired by Caroline Pidgeon, has recommended tougher rules requiring the Mayor and assembly members to declare potential conflicts of interest - in the light of allegations that Boris Johnson gave preferential treatment to Jennifer Arcuri.
Caroline told the BBC:
It's got to be right that when public money is being spent on things like overseas trips and opportunities for your business, it's got to be so transparent and so squeaky clean, to make sure that nobody can ever point the finger at a Mayor of London or even an assembly member to say "Your mate had access there". That's what we've looked into, and I think we've come up with some strong recommendations to take this forward.
And hear Caroline discussing the report with BBC Radio London's Jim Davis.
