Duncan Bannatyne has had a dig at Dragons' Den colleague James Caan over his tax status.
The Scottish tycoon is accusing his fellow millionaire of having an "unfair" business advantage because he is non-domiciled - meaning he does not pay UK tax on his overseas earnings.
It comes as Caan muscles into Bannatyne's health club territory, with plans to open a series of new fitness and leisure premises across the country.
