Boris Johnson will court controversy this week by taking Rupert Murdoch to an Olympics event as his personal guest.
The News Corporation boss is among a group of business leaders London's mayor has invited to attend a swimming final on Friday that is expected to feature British star Rebecca Adlington.
As mayor, Mr Johnson has oversight of Scotland Yard, where a police investigation into the phone-hacking scandal that has engulfed the media mogul's newspapers is still under way.
Mr Johnson's decision to invite Mr Murdoch and his wife Wendi Deng will be seen as a deliberate attempt to demonstrate his independence from David Cameron, who has distanced himself from Mr Murdoch since setting up the Leveson inquiry into media standards and ethics.
Mr Johnson, who initially described the phone-hacking investigation as 'codswallop', is thought to have invited Mr Murdoch because of investment in British sport by his firms - particularly BSkyB - over many years. It is believed to be a 'long-standing invitation' that was also extended to other media executives.
