A Walsall couple and their fathers, along with two others have been sent for trial for plotting to defraud The Royal Bank of Scotland and HSBC.
The conspiracy, involving hundreds of thousands of pounds, is understood to have been carried out with the help of fake invoices and a factoring agreement. The eight-week case will start at London's Southwark Crown Court on March 3.
Among those in the dock for a plea and case management hearing today were Rachael Baker, 35, of Sunflower Mill, Walsall, and her husband Timothy, 35, from Wolverhampton Road, Walsall.
Alongside her were her 65-year-old father, Paul Smith, who lives at Woodlands, Ironbridge, Shropshire, and father-in-law, Alan Baker, 57, of The Red House, Lydbury North, Shropshire.
Also before the court were former company directors Stephen Lawrence, 41, of Southborough Road, Chelmsford, Essex, and Mark Starling, 35, of High View Crescent, Hutton, Brentwood, Essex.
They variously deny two counts of conspiracy to defraud and two of laundering criminal property between December 31, 2005, and August 5 last year.
A seventh defendant, Stephen Roberts, 47, of Goldthorn Park, Wolverhampton, was not in court. He faces all four counts and will be arraigned at a later date.
