"should be accessed outside the UK by contractors working on the capital's congestion charge scheme"
So the big, and imo only, question here is why are govt agencies using public funds to pay companies in foreign countries to do sensitive work when we have a liquidity and employment crisis?
The whole outsourcing thing is a huge betrayal of your country.
1) We don't have much money in circulation, wtf are people doing sending it all abroad and out of the UK economic eco-system?
2) We're short of jobs why isn't the govt thinking to give some to residents in all it's grand plans to introduce Victorian style labour regs which even the greedy super companies think are a disgrace.
but for the IT angle:
3) Given the monumental f-up that is UK govt IT at every turn how can they have the front to say they want to expand the scope for data loss/theft?
