If Whitehall can't close ID Cards, what hope 25% Govt-wide savings?

By the end of the summer the Identity Documents Bill should become law. 

Its aim, which is consistent with the pledges previously made by both the Conservatives and the Liberal Democrats, is to repeal the Identity Cards Act which the Labour government passed in 2006.
But there are hints in a Cabinet Office document that it may not be easy in practice shutting down ID Cards or the Contactpoint database.  
Indeed the Cabinet office makes no commitment to shutting down either scheme – it leaves open the possibility of “rehshaping” them
The Cabinet Office “Structural Reform Plan” was published last week. It’s an impressive plan.

On ICT plans it says:
– Increase powers of CIO to drive the integration and improve value for money of ICT infrastructure
– Set up infrastructure for new CIO office and increase central CIO powers
– Start the roll out cross-departmental asset register on a common ICT infrastructure
– Publish performance details on all ICT projects above £1m 
– Conduct negotiations with suppliers to reduce annual ICT spend immediately
– Create new procurement process with Treasury
– Identify cross-department pipeline of upcoming /ongoing tenders/negotiations through the moratorium and project review
– Agree with Treasury conditions under which a project is “released” from moratorium
– Work with OGC to develop a new approach to ICT procurement enabling greater use of SMEs, a much shorter timescale and lower costs to all parties
– Identify ICT projects/programmes to terminate and organise/assure decommissioning
 – Identify computer systems for decommissioning, then conduct decommissioning with departments
– Reduce the cost structure of information and communications technology in central government, while supporting technologies which increase citizen involvement, transparency and localisation.
The plan has a start and end date for each of the objectives. On ICT plans, most of the objectives listed above have ambitious end dates of this year.
But on the government promise to scrap  ID Cards and Contactpoint, the plan says:
– “support Department for Education and Home Office in decommissioning/reshaping ContactPoint and ID Cards”
Comment: If it’s so difficult to shut down ID Cards and Contactpoint – a manifesto commitment – will the government achieve the much more ambitious objective of average 25% departmental savings over four years?
