Bulgarian nationals, Galina Nikolova, 38; Stoyan Stoyanov, 27; Tsvetka Todorova, 52; Gyunesh Ali, 33; and Patritsia Paneva, 26, have pleaded guilty to fraud and money laundering related offences at Wood Green Crown Court for their involvement in a multi-million-pound scam on the benefit system.

Ben Reid, specialist prosecutor for the CPS, said: “This case is the largest benefit fraud prosecution ever brought to the courts in England and Wales.

“For a number of years, these defendants conspired to commit industrial-scale fraud against the Universal Credit system, costing the taxpayer more than £50 million.

“Submitting thousands of false claims, the organised criminals enriched themselves from government funds designed to protect and help the most vulnerable people in our society.

“This was a complex and challenging case which required close and effective working between CPS prosecutors, the Department for Work and Pensions and our international partners in both Bulgaria and through the UK desk at Eurojust, to dismantle and successfully prosecute the organised crime group. The guilty pleas entered by all five defendants, reflects the strength of the evidence against them.

“The CPS Proceeds of Crime Division and DWP will now pursue confiscation proceedings against the defendants, to remove from them any available criminal benefit from this enterprise.”
