The Premier League is believed to be consulting lawyers over claims that Ukip’s logo is a “rip-off ” of the emblem of English football’s top flight.
A Ukip spokesman insisted the design “is not a rip-off ” and stressed that Ukip had checked that it does not infringe copyright.
The logo has sparked a war of words between Gary Lineker and Ukip.
The Match Of The Day host tweeted the message: “The #premierleague will be thrilled.”
The Ukip spokesman then commented: “Gary Lineker is a somewhat sanctimonious, well-paid TV celebrity who has their own opinions.”
