" Both the Hawk and Scorpion deals were underwritten by the ECGD. Indonesia has never paid for the aircraft and vehicles, as the payments were rescheduled in 1998 following the Asian financial crisis. After 1998, the ECGD paid out £645 million for bad debts relating to arms sales to Suharto—about £400 million to BAE Systems for the Hawks, £93 million to Alvis for the Scorpions, and £150 million to other UK arms companies (
Guardian, 20.12.04). Currently, Indonesia owes the UK £551 million in military-related debt (
Hansard, 10.1.05). Of this, £80.7 million is for the Scorpion and Stormer vehicles and £382.7 million for the Hawks (Hansard, 13.1.05). Payment of the debt by Indonesia to the ECGD is not expected to finish until 2021, and there is every likelihood the money will never be recovered "
