The Pirate Party UK is now an official British political party, having been registered with the electoral commission. According to the Party’s blog:
Enthusiastic support for the party has, up to now, sometimes blinded us to the fundamental truth: there was no party. The Pirate Party UK existed only as an idea. But now it is real, and here to stay for as long as it is needed. At the end of last month, the Electoral Commission confirmed the registration. You can see the PPUK entry on the official register.
Now the party needs you. Yes, I know you were there for the party all along, but now you really can join this real political party. We are about to set sail and it is time to climb aboard. It is going to be one heck of a journey.
