Rupert Murdoch, the conservative media mogul whose New York Post tabloid savaged Hillary Clinton’s initial aspirations to become a US senator for New York, has agreed to host a political fundraiser for her re-election campaign.

The decision underlines an incongruous thawing of relations between Mr Murdoch and Mrs Clinton, who in 1998 coined the phrase “vast rightwing conspiracy” to denounce critics of her husband, such as Fox News, the conservative cable channel owned by Mr Murdoch’s News Corporation.
