Been sent a debt collectors letter from a parking fine

[Ricochet J]

Few months ago my brother borrowed my car and he admitted he received a parking fine. However, the car park where he parked was a private car park with allocated parking slots. He parked in his friends slot and told the ticket issuers this but they say the ticket still stands. He refused to pay for the charge as he says he received permission from the owner of the slot

He said any letters addressed to me on my name regarding the fine I should forward to him - fair do's. (I get the letters and invoices for charges since I'm the owner of the vehicle).

Now, I've received a letter from a "Roxburghe Debt Collectors" threatening legal action from "Graham White Solicitors" if payment isn't made within 7 days.

My brother is out of the country for at least two weeks so I can't forward the debt letter. (I've e-mailed him, his telephone num doesn't work where he is, so I'm trying to call his friend who lives in the country.)

Advice? Shall I ignore the letter? Shall I send a reply stating I'm legally not the one that should be invoiced?

Thanks

P.S - Please no posts slating my brother.

Money Saving Expert seems to say the invoice is non payable and I should ignore any correspondance.
