GG accepts the "i don't drink" letter was from him in this interview

There's also a mention in one of the Mail articles of Galloway being asked about the letter. His reply, apparently, was that he would never have mentioned anyone's religion, but for the Labour attempt to use religion to get votes.
The letter is shown on a variety of sites and partially quoted in various articles.
The oddest thing is that anyone should think Galloway would NOT put out a letter of that sort.
* His comments on the Labour campaign are, I bet, true
* His innuendo about the Muslim Labour candidate's drinking matches tittle-tattle that you can read elsewhere. Why would Galloway not use that?
* The bulk of the letter consists of stuff that he has come out with before
* For example, all the stuff hinting that he's a Muslim, but stopping short of explicitly asserting or denying it, matches what he has done before in interviews
* The focus on "I, George Galloway" is just his style
* The boasting about some Pakistani honours he was awarded (awards that may be meaningful to Pakistanis, but are unknown by most Britons) is in character
* The wretched Islamophilia and pro-Palestinian blather, the focus on his own claimed bravery etc etc is all Gallowayesque
If it had turned out that someone had faked that letter, I would have been amazed and very impressed by whoever did it. It is Galloway to a fucking T! As far as I can see, it is only on U75 that people don't believe it's Galloway's letter.
