Unlike non-UK readers, most of us in the UK will probably think of the budget fashion store, Primark. The term Primarni is itself derived from Armani, to make Primark "sound more posh". Slang permeates British society so much so that it becomes second nature for much of the population.
I find this term a sign of typical Britishness: wanting to make something sound high class by displaying an ironic humour. It has been created by the public and, as far as I am aware, is not used directly by Primark.
On another note, it seems the domain name primarni.co.uk was registered by a furniture company back in 2007.
Primark are a heavily branded company - comparable to Lidl's own multi-branded products for food - and they own a significant number of (used) trade marks.

Incidentally, on 7 December, just five days following publication, a Notice of Threatened Opposition was filed against the application. The IPO records do not indicate the Threatening Opponent.
