I would stay off the politics with Carillon , all sides are guilty on that one , Tory invention was the PFI expanded exponentially by Blair/ Brown . carillon was the almost bankrupt Tarmac bunged together with Mowlem . They did some huge projects Drax, Channel Tunnel , Thames Barrier etc , they had an awful reputation for 120 day from invoice payments , but could take twelve months to sign off the invoice , two years from job finish to payment was common . to monopolise the public sector they would tender at cost , then screw the job on the extras and variations in 1999 they metamorphosed into Carillion , same tactics . if job 1 is losing job 2's money will pay for it because of their size and tendering they get the work ,KPMG as the auditors must have turned a big blind eye to 18 years of this ,
