Populist MP Geert Wilders is writing a book about the history of Islam that argues it is not a religion but an ideology.
The book, which was to be published in the first half of 2011, is now due to appear in the second half of the year, Mr Wilders told news website NU.nl.
The initiative for the book, Mr Wilders says, comes from the United States, where it will appear first, to be followed by a Dutch translation.
Mr Wilders also revealed he is working on a continuation of his short anti-Islam film Fitna, but he couldn't yet say when it would be completed.
Regarding the unrest in the Arab world, the far-right politician claims that democracy will not take hold in the Maghreb and the Middle East unless people turn away from Islam.
He warned that things could go either way and the future could see regimes that are even worse than those of ousted Presidents Hosni Mubarak of Egypt and Zine al-Abidine Ben Ali of Tunisia or that of Libya's Colonel Muammar Gaddafi.
