A good example of this would be the scandal in the UK involving David Blunkett (Labour MP) in 2004 when it emerged that he had fast-tracked a visa application for the nanny of his ex-lover. I take this to be an abuse of power, as he took advantage of his position for a personal favour. Although he denied having any part of it, Blunkett recognised that he had to take responsibility and consequently stepped down as Home Secretary.
