Britain's National Westminster Bank has frozen the account of a principal Iranian propaganda arm, PressTV.

No explanation has been given publicly or, apparently, to PressTV. "They're not giving any reason why they've done it," said attorney Matthew Richardson. Britain and the U.S. have worked to cut off access to bank accounts and other financial outlets for Iranian government enterprises as part of a program aimed at getting the country to give up its nuclear weapons program.

Last summer, Barclay's Bank agreed to pay nearly $300 million in fines for allowing Iran and other terror-sponsoring states to move hundreds of millions of dollars.

Writer Shiraz Maher calls the move "a welcome development," noting that PressTV "has a long track record in producing agitprop for the Iranian state, including the lie that Neda Soltan's murder by the regime was a hoax."

He notes that National Westminster still provides services to Viva Palestina, the brainchild of former MP George Galloway that organizes aid caravans to Gaza which benefit Hamas. Galloway has two programs on PressTV, one called "The Real Deal," and another called "Comment."

Press TV's website carried a report today that Iran threatening to cut off relations with Great Britain for its "meddlesome and undiplomatic approach toward Tehran. "
