Mohammed Hamid, 50, worked with Abu Hamza's right-hand man, Atilla Ahmet, 43, described as 'the number one al Qaeda operator in Europe'.
Hamid trained the 21 July bomb gang at 'remote camps' across Britain.
A BBC documentary crew filmed one terror camp for the show Don't Panic I'm Islamic.
Hamid reportedly trained the failed 21 July London bomb plotters Muktar Said Ibrahim, Ramzi Mohammed, Hussain Osman, Yassin Omar and Adel Yahya at a farm in Great Langdale, Cumbria, in 2004.
Hamid reportedly organised a paint-balling trip attended by Mohammed and Osman in July 2005 near Tonbridge, Kent, just two weeks before the failed London bomb attacks.
