As of now there is no existence of Tata Motors in UK, but there are speculations that harrier will launch it as a global player which will be launched in UK.
But the thing I don't understand stand is that Tata is having a range of brands which were bundled with the purchase of JLR from Ford. Rover is one marque that has historical connection with the people in UK and will get attached to that, simple rebadging if these products will be enough.
