No matter who is asking, ASA hasn't got a snowflakes chance in hell of getting the contract. The Bahrain contract would be one of the better managed contracts in the Gulf ( I am talking contract management here not operational management as that is another discussion completely), and they seem to retain staff a lot better than we do here in the UAE (something to do with Villas being provided and less penny pinching than goes on here, from what I hear).
Serco will remain in Bahrain until further notice and the only reason the Bahrainis opened the process up for other bidders is to keep Serco honest with their bid.
PMS I guess you'll have to look elsewhere for an opportunity to get back into the Gulf.
