The rising London rap star on the left, and the ISIS executioner on the right are the same person, according to MI6
The review also shows just £50,000 worth of assets was frozen in bank accounts opened by terror suspects operating in the UK. The amount was branded "remarkably low" by David Anderson QC, the Government's independent reviewer of terrorism legislation and author of the new study.
Mr Anderson's report into 'the operation of terrorist asset-freezing' lays bare the Coalition's failure to seize jihadists' money under the Terrorist Asset-Freezing Act (TAFA) 2010.
His findings will be seized upon by critics who have complained the Coalition has failed to crack down on terror financiers.
The report says more than 600 British-based jihadists have travelled to Syria and Iraq to fight with the Islamic State of Iraq and the Levant (Isil) and other terror groups such as al-Qaeda but only six currently have their assets frozen.
They are: Nasser Muthana, 20, and Reyaad Khan, 21, both from Cardiff, and Ruhul Amin, from Aberdeen, who all appeared in an Isil recruitment video last summer, which sparked widespread outrage.
Muthana's 17-year-old brother Aseel Muthana has also been added to the list, having also fled to Syria.
The fifth man on the list is Nur Idiris Hassan, 21, from Manchester, who fled the UK for Syria last year with the help of chemistry teacher Jamshed Javeed who has since pleaded guilty to terrorist offences.
A further unnamed terror suspect believed to be linked to Isil is the sixth man on the list.
In total just 25 individuals are on the UK Treasury list.
Mohammed Emwazi, a former London schoolboy who was unmasked as 'Jihadi John', the Isil executioner, is one of hundreds who has escaped a freezing order. Emwazi does not feature on any of the asset freezing orders issued by the Government.
More than 300 British jihadists who fought in Syria and Iraq and have since returned to the UK are also now free to continue using their bank accounts, despite the fact they will have been identified by security services as terrorists.
Those accounts can be used to fund terrorist activity in the UK as well as pay for extremists to travel to the Middle East.
The report will put pressure on the authorities to do more to clamp down on the cash supply line to fanatics. A Telegraph campaign has previously highlighted the serious shortcomings of The Treasury's terror sanctions list.
In his report Mr Anderson said: "The figures for assets frozen are remarkably low."
