The six-strong group was a mixture of British and foreign born Muslims all living in Birmingham. Omar Khan, 28, Mohammed Hasseen, 23, both of Sparkhill, and Mohammed Saud, 22, from Smethwick are British. Jewel Uddin, 27, of Sparkhill was born in Bangladesh while Zohaib Kamran Ahmed, 22, of Alum Rock and Anzal Hussain, 24, of Moseley, were born in Pakistan.
The group planned to target an EDL rally in Dewsbury on June 30 last year and turned up heavily armed with explosives, two shot guns and up to a dozen knives and machetes. EDL leader Tommy Robinson was due to speak at the event, which involved up to 700 supporters, and it was expected to run all afternoon.
The terror group did not arrive in the town until 4pm, by which time the EDL demonstrators had left.
It was on the journey back to Birmingham that the police and security services had their second stroke of luck. Khan and Uddin were travelling in a Renault Laguna that they believed had been insured for that day. A South Yorkshire Police traffic officer on routine patrol on the M1 motorway made a check on the vehicle and it flashed up as having no insurance.
It later transpired that Saud had made a slight error in the registration number when taking the policy out meaning it was not on the records. The officer stopped the car and ordered it be impounded but even then the true scale of what he had stumbled across was not known.
The car was taken to the Woodhead Motors pound near Sheffield and sat there for two days before an inspection by staff unearthed a terror cache. In the boot were two sawn-off shotguns, ammunition and a selection of knives and machetes. When police arrived, they also discovered a homemade bomb adapted from a regular firework and three small, partially constructed pipe bombs.The firework contained more than 350 nails and 187g of explosive, made up of twice the number of explosive pellets normally found in the rocket.
There was also CDs containing Islamic extremism, including lectures by the al-Qaeda fanatic Anwar al-Awlaki.
Crucially for the police, officers also found ten copies of a letter which spelt out the gang’s plans to attack the EDL and which was addressed to the Queen and David Cameron.
Uddin had been under watch by MI5 after he had been investigated during a separate plot in 2011 by a Birmingham gang to attack the UK with eight suicide bombers. The three ringleaders of that group were convicted earlier this year and others either pleaded guilty or await a further trial.
There was insufficient evidence to link Uddin, who had been seen carrying out street collections with members of the other terror gang, with the plot.
Sources insist there was no intelligence to link Uddin with the others or anything to indicate a coherent group. There was also no intelligence to suggest a plot to target the EDL.
Analysis of computers seized after the arrests showed the group had researched the EDL in depth, including details of Mr Robinson, for up to a month before the rally. They had also researched an EDL rally held in Rochdale on June 9 before turning their attention to the Dewsbury one.
Copies of a letter, likely to have been distributed during or after the attack, also insulted the Queen as a “kuffir devil” and said the EDL or “English Drunkards League” was being attacked in retaliation for blasphemy of Allah and the prophet Muhammed.
Although it remains unclear whether the terrorists planned to martyr themselves, the letter, which was addressed to the Queen and David Cameron, added that they “love death more than you love life."
