As his superiors betrayed the liberal Muslims of the Middle East, Mockbul Ali worked to marginalise their counterparts in Britain. Although the domestic affairs of our country are not any of the FCO's business, it sponsored a road show, which purported to be representative of British Muslim voices but was in reality a Muslim Brotherhood front. Ali followed up by lobbying the Home Office to allow extremists into Britain. Eric Taylor, of the India-Pakistan
Relations Desk, was one of the few officials to protest. He pointed out that a gruesome Bangladeshi politician Ali was recommending had provoked riots on his last visit and, according to a report from a Bangladeshi human rights organisation, Drishtipat, had compared Bangladeshi Hindus to excrement, while appearing to defend attacks on the country's persecuted Ahmadiyya Muslim community, regarded as apostates by the Islamists.

The more Pasquill read, the more driven he became. He roamed the FCO's corridors picking up Ali's files, first taking them to Soho to copy and post, then just emailing them home and printing them out. I won't say that his leaks had no effect. The story went round the world. In Britain, Hazel Blears, Ruth Kelly and Jacqui Smith — all women, significantly, who were appalled by the official endorsement of misogyny — read Bright's reports and tried to save what was left of the honour of the British Left by fighting back. But I cannot pretend that their stand was anything other than an isolated example. Pasquill's revelations had no impact on a wider liberal society. It did not want to see how hypocritical it had become or to survey the damage it had wrought. The achievement of political Islam in Britain has been to suborn the liberal Left and cut off the most promising escape route for dissidents in the process. An abused woman, a young man fighting religious authoritarianism, an Iranian exile seeking to gain support for the campaign against the Archbishop of Canterbury's and Lord Chief Justice's endorsement of Sharia law or a British Bangladeshi trying to bring the Islamist criminals who massacred civilians in the war of independence to justice, would once have looked left for succour. If they do so now, they will find that progressives take their cue from the Muslim Brotherhood and Jamaat-e-Islami, rather than the best of the liberal Left's traditions, and dismiss Muslims who fight for values they profess to hold as being at best irrelevances and at worst stool-pigeons for imperialism.

Do not make the mistake of believing that such attitudes are confined to the FCO. Only recently, the supposedly left-wing Institute for Public Policy Research was trumpeting "non-violent" Islamism as "the best organised and most popular opposition to existing authoritarian regimes in the Middle East". What "non-violent" Islamists would do to Arab liberals when they achieved power was not a question that detained the British leftists of the IPPR for a second.

As his illusions about the benign nature of the FCO crumbled, Pasquill tried a thought experiment. He asked himself, "Is the Foreign Office a Muslim Brotherhood front organisation?" Obviously, it was not, he replied, although looked at in a certain light, it might as well have been. The light metaphor stayed with him until "one day I was looking at the ivy growing in my garden and it struck me that it was phototropic — growing in the direction of the sun. I realised that the FCO is Islamotropic: it grows towards Islamic extremism, always searching for reasons to excuse it." At the age of 50, Derek Pasquill is now on the dole with no pension, no savings and no prospects. The FCO responded to his revelations by promoting Mockbul Ali. Like ivy on a wall, the liberal establishment still creeps towards the reactionary forces that despise it, entwining itself with its enemies and leaving its friends to wilt in the dark.
