The left lost not a minute in tarring Sarah Palin after McCain selected her as his running mate. Of course they had to be careful-very careful. As hard as they worked, they couldn't dig up anywhere near as much dirt on this outstanding self-made governor than they have all along covered up for their darling Obama.

What did they do? The cunning leftists are nothing if they are not devious and Machiavellian. It would have been a huge self-inflicted disaster if the men had led the offensive. So, true to form, these unscrupulous leftist cowards hid behind their women's skirts and let them do their dirty work.

Women vilifying a woman, no matter how baseless and vicious the assaults may be are better tolerated than men doing the dishonourable thing-they are chalked to the nasty game of partisan politics. To the leftists, as is the case in war and love, all is also considered fair in politics.

Here is a woman, by all accounts, a personification of the American story. A self-made woman rising from the heart of the middle class, distinguishing herself as a tireless devoted public servant who had worked through the grades to the governorship post by single-mindedly remaining faithful to the trust of her electorate.

Here is a woman who had no sugar-daddy sponsor to send her to an Ivy League school, but had to work hard on her own with the support of her not-so-wealthy working parents to finish college.

Here is a woman who took on the powerful corrupt officials at the state level. She confronted corruptions and the old-boys network. She even challenged the miscreants in her own political party and took on an incumbent governor and beat him without selling herself to the powerful interest groups.

In a large balcony above the beautiful main hall at Regent's Park Mosque in London - widely considered the most important mosque in Britain - I am filming undercover as the woman preacher gives her talk.

What should be done to a Muslim who converts to another faith? "We kill him," she says, "kill him, kill, kill...You have to kill him, you understand?"

Adulterers, she says, are to be stoned to death - and as for homosexuals, and women who "make themselves like a man, a woman like a man ... the punishment is kill, kill them, throw them from the highest place".

These punishments, the preacher says, are to be implemented in a future Islamic state. "This is not to tell you to start killing people," she continues. "There must be a Muslim leader, when the Muslim army becomes stronger, when Islam has grown enough."

A young female student from the group interrupts her: the punishment should also be to stone the homosexuals to death, once they have been thrown from a high place.

These are teachings I never expected to hear inside Regent's Park Mosque, which is supposedly committed to interfaith dialogue and moderation, and was set up more than 60 years ago, to represent British Muslims to the Government. And many of those listening were teenage British girls or, even more disturbingly, young children.

My investigation for Channel 4's Dispatches came after last year's Undercover Mosque, which investigated claims that teachings of intolerance and fundamentalism were spreading through Britain's mosques from the Saudi Arabian religious establishment - which is closely linked to the Saudi Arabian government.

In response, the Kingdom of Saudi Arabia denied it was spreading intolerance, while Regent's Park Mosque, which featured in the film, urged all mosques to be "vigilant" and monitor what was taught on their premises.

So earlier this year, dressed in a full Islamic jilbaab, I went back to Regent's Park Mosque to see what was being taught there. As a woman, I had to go to the main female section, where I found this circle preaching every Saturday and Sunday, eight hours at a time, to any woman who has come to pray.

Muhammad ruled with an iron fist while alive and no one contested his authority. He designated no heir, and left no will, oral or written, and had no male issues from any of his wives and slave women to inherit the office. Some believers, however, felt that the prophet wished for Ali, his cousin's and son-in-law, to assume the Ummah's leadership while a vast majority opted for the Arab's traditional patriarchal seniority-based practice by choosing Abu-Bakr as the Caliph.

Abu Bakr, Muhammad's oldest high disciple and the father of Muhammad's nine-year-old child-bride Ayesha, assumed the position of the first Caliph and died shortly thereafter. He was followed by Umar ibn al-Khattāb, Uthman ibn Affan became the third Caliph, and finally by Ali ibn Abu Talib.

Ali was considered by his admirers to be the greatest Muslim warrior and by his detractors as a vicious killer. Two of Ali's sons, Hassan and Hussein were viewed similarly. Ali was murdered, according to one version, by one of his own followers who resented Ali's capitulation to the Caliphate hierarchy. That is, the assassin and his like-minded Muslims felt that Ali betrayed Muhammad by not fighting to be his immediate successor and by consenting to be the fourth Caliph. Another version of his death is that a Persian warrior by the name of Brahman Jazyyeh killed Ali, avenging the death of numberless Persians that Ali and his people had slaughtered.

Ali reportedly killed untold numbers of Islam's enemies, including Persians, with his much-feared sword that had its own name: Zulfiqar. He was addressed by his followers as Amir-ul-Momeneen (Commander of the Faithful).

Speakers present included Sajjad Khan on "Realising Political Unity", Dr. Mahmad Salim on "The Shariah and Unity", Sister Sultana Parvin on "Scientific and Educational Potential under the Khilafah State", Jamal Harwood on "Economic Development through Unity and Khilafah policy" and Imran Waheed on "Pakistan- an application of Unity and Khilafah policy". The relatively unknown, loss-making satellite television station, Islam Channel, was present to record proceedings.

As at all other Hizb ut Tahrir al Islami events, there was much talk about bringing back the Islamic Caliphate which finished in 1924. Much discussion about how neither democracy nor dictatorship worked and how Khilafah was the only workable solution compatible with Islam. No one version of Islam was mentioned and no mention of which caliphate to revive was ever referred to. The great successes of democracy and certain dictatorships swept aside as if human progress depended purely on algebra. Always the first law in misleading advertising is to avoid the concrete and plant the vague - the speakers as deceptive as Sweeny Todd in their spinning of illusions.
