The Big Tent Israel conference in Manchester this month would have to be a very big tent indeed to include one name I spotted among a list of possible speakers for the event: the Reverend Stephen Sizer.

Israel has faced few more vocal antagonists in the Christian world than the author of such books as Christian Zionism: the Road to Armaggedon?

The organisers assure me his inclusion was a mistake by a conference aide typing up the list.
