The organisation, which has millions of followers worldwide, insists that it is a peaceful, apolitical revivalist movement that promotes Islamic consciousness among individual Muslims. However, intelligence agencies have cautioned that the group’s ability to fire young men with a zeal for Islam acts as a staging post, for some, along a path that leads to jihadist terrorism.

Tablighi Jamaat, an Islamic extremist movement, abandoned its traditional dislike of modernity and politics in support of its plans to build a London mosque with a capacity for 12,000 worshippers.

The group behind the plans is Tablighi Jamaat, a Muslim missionary sect whose charitable trust, Anjuman-e-Islahul Muslimeen, has owned the 18-acre site since 1996. Tablighi Jamaat was called “an ante-chamber for fundamentalism” by French security services. Two of the July 7 London suicide bombers are believed to have attended one of its mosques.

A massive mosque that will hold 40,000 worshippers is being proposed beside the Olympic complex in London to be opened in time for the 2012 Games.
