Is a taxi a form of public transport? Seems borderline to me, and I guess there are arguments for and against. Depending what your view will define how you interpret the following.
Apparently, between 2007 and 2009, the central Department of Transport, spent £281,764 on taxis. Interestingly, according the minister Chris Mole, one of the other agencies of the department, the Government Car and Despatch Agency does "not record taxi fares separately from other travel costs".
That's awfully lucky I think , because if it did, and the agency responsible for providing cars as a means of transport to the Government was splashing out on taxis it would be rather embarrassing.
