The British Phonographic Industry (BPI) has sent a letter to the Pirate Party UK chief Loz Kaye requesting to close their Pirate Bay proxy service.

Kaye told TorrentFreak he is yet to receive anything other than an email and was only aware a letter had been sent when he received requests for comment.

"The first I was aware that such a letter had been sent was when I received requests for comment from journalists. The BPI have laid out their position and asked for our response, we intend to respond by the 6th of December," Kaye said.

The letter sent by the BPI focuses on Pirate Party UK’s comments about freedom of expression.

BPI chief executive Geoff Taylor was quoted by BBC as saying that "Freedom of expression is not an absolute right."

"It comes with a duty to respect the rights of others, including those whose talent, hard work and investment help to create music and other entertainment," Taylor said.

In October this year, BPI had asked UK’s major internet service providers (ISP) to add three more file-sharing websites to the piracy blockade list.

BPI claims that three sites including Fenopy, H33t and Kickass Torrents have been involved in illegal music distribution.

Earlier this year, UK high court ordered several country’s ISPs to block access to the file sharing site, Pirate Bay.
