The 30-year-old, whose real name is Stephen Yaxley-Lennon, pleaded guilty to two counts of conspiring with others to obtain a mortgage by misrepresentation, the BBC reported.
The fraud, which took place in 2009, was directed against Abbey and Halifax. He will be sentenced in the New Year.
Yaxley-Lennon founded the controversial protest group the English Defence League in 2009 using the pseudonym of Tommy Robinson. While the group’s supporters include far-right sympathisers and football hooligans, Robinson repeatedly denied claims the group was Islamophobic. However he left the group last month citing the dangers of ‘far-right extremism’.
In January, Yaxley-Lennon was jailed for 10 months after admitting he used a false identity to travel to the United States.
