Not sure if this will help but if you contact the chap below he may be able to help you with the POA. He is based in London and has runners to take the POA to the embassies and consulates for stamping etc... Costs money but better than traveling down to London and you sometimes need two trips to the embassy, and if you sent by post to be done it can take weeks and weeks. I sent one for a client in Bulgaria and it took almost 2 months just to get it back from the Foreign Office. Anyway here are his details if anyone needs them, give him a call he is a nice guy.
