BORIS Johnson likes to make much of the fact that he has convinced the private sector to give him oodles of cash. Barclays gave £25m to help pay for his Boris bikes while Emirates, the airline, will pay £36m over the next ten years to sponsor the Thames cable car. But his method of extracting cash from benefactors can sometimes prove a little unconventional. The Capitalist hears that he tapped Lakshmi Mittal for cash while the pair were taking a leak at a urinal in Davos, where they were attending 2010’s World Economic Forum. Just two months later, Mittal said he was donating £16m to help build the UK’s tallest sculpture, designed by Turner Prize-winning artist Anish Kapoor, to commemorate the London 2012 Olympics.
