Six solicitors - including two part-time judges - are among nine people charged in relation to allegedly fraudulent legal aid claims that were made for more than £12.6m.

According to a Metropolitan Police statement, the charges follow a complex fraud team investigation, which began in December 2012 after HM Courts & Tribunals Service reported allegedly fraudulent applications for legal costs made to the National Taxation Team. The Crown Prosecution Service has authorised charges in respect of four claims made between January 2011 and September 2013.

The Metropolitan Police said that, in these cases, claims in excess of £12.6m were made. In total, £1.4m of public funds was paid out and it is alleged that the majority of this money was fraudulently obtained.

The Metropolitan Police confirmed that nine people have been charged by postal requisition.
