Quite a number of people over the last few days have been talking about Newsnight's story that, essentially, because a couple of receipts that Policy Exchange gave them (after it had produced its report on the sale of extremist literature in mosques) might be dodgy the entire report is flawed. As one would expect, the usual suspects on left wing blogs have written long essays about it all.
Anyhow, this morning the Chairman of Policy Exchange, Charles Moore has gone after the BBC in the Telegraph. He's basically said that the Newsnight team have been underhanded and also suggests that Paxman had not been briefed properly resulting in him saying untruths on screens.
Worst though is the news that the BBC indicated where the anonymous Muslim researchers behind the Policy Exchange were from, and now an Islamist website has had calls on it to hunt them down. If they succeed then it will be the BBC that has blood on its hand then.
