Dyfed-Powys Police said the pair were arrested under the Data Protection Act as part of a joint investigation with the Information Commissioner's Office. They are due to appear in Nottingham Magistrates Court on September 1.

The far-right BNP called for a police investigation last November after the names, addresses and contact details of some 10,000 of its members were published online. Party leader Nick Griffin lodged a complaint with Dyfed-Powys, his local force, on the grounds that publishing the list breached human rights and data protection laws. He described the publication as "a disgraceful act of treachery" by former BNP staff members who were subsequently sacked.

At the time the BNP said the leak was based on its 2007 membership list. It featured details of some members' jobs and was reported to include serving and former police officers, as well as members of the armed forces.

In a statement, Dyfed-Powys Police said: "We can confirm that the two people arrested in relation to alleged criminal offences under the Data Protection Act have been charged with Section 55 Data Protection Act offences. The arrests followed an investigation into a complaint received about the unauthorised release of the BNP party membership list."

The Indie has confirmed it's Sadie Graham but nothing on the man yet.

Gri££in described the leaking of the list as, quote "a disgraceful act of treachery"
Well he'd know I guess. This is the one area the scumbag is expert in!

Good luck in court to whoever was arrested for doing this.

WTF? Matt Single is in his late thirties, so who is the 27 year old who has been charged along with SG?

Sadie Graham used to be an antifascist hunt saboteur in Brighton - maybe she was infiltrating the BNP all along? I know if I was in the BNP I wouldn't trust her as far as I could throw her.

I don't know if you are repentant fascists, a splinter-faction of fascism or infiltrators. Those distinctions are important to me, but what is more important is that your action helped save my and my famlies lives.

I was car-jacked by my local BNP gang - really, they are just a nasty gang here - and held hostage for 24 hours. I was drugged, imprisoned and threatened with various deaths for 24 hours but I talked my way out of that.

When the BNP membership list was published I was able for the first time to identify the streets the main gangsters came from. This has helped me avoid these gangsters and for that I am grateful regardless of your motivation.

In response to the various right-wing 'libertarians' who suggest everyones political allegiance should be made public, I fully agree. I'd like to know all the political parties databases and can't see any reason for that to be private. If you've nothing to hide...

Sadie was also in a relationship with the bloke who run Newcaslte AFA and one of my mates sucked her tits.
