NEW YORK: Fox News has cancelled the show of Lou Dobbs, a right-wing presenter with a history of airing baseless conspiracy theories and one of the most ardent supporters of former president Donald Trump among US broadcasters.

The decision on Friday came a day after Fox News and Dobbs were sued for defamation by voting technology firm Smartmatic, which is claiming $2.7 billion in losses from the network for promoting false claims that the company was involved in fraud in November’s presidential election.
