Nike is threatening to sue Scottish Courage over the "Just 'ave it" slogan currently being used in a John Smith's advertising campaign.

The sportswear manufacturer also claims John Smith's revamped horseshoe logo resembles the Nike "swoosh".

Nike's said that the £10m campaign is "detrimental to Nike's trademarks, which are registered in the main for sports clothing, tarnishing them and making them less attractive and less distinctive".
