I do not think so somehow
Well we know that one there plans would be for local GPs to manage there IT systems, presumable keeping the data stored locally, well that what cameron said in one of his speeches, in a GP building which are usually unsecured an easily broken into, one of the locals ones be done twist in that last year.
Give than they are also unlikely to have anyone above them to check that there passwords are to scratch, security software are updated regularly, an consider my local GP secretary writse her passwords on a piece of paper which is left it on the desk for the world to see, hell I could of swipe the peace of paper an she probably would not even notice, I would bet security would be a utter disgrace if the conservatives get there way. Also local GPs are run like a business nowadays, an are generally very efficient which is why they can afford to pay themselves so much. I can guarantee many of them will go for the cheapest one they can buy.
Also under conservatives plans they have yet to announce how much there ideas will cost or how long it will take to implement there plans, this despite an 6 months review into the nhs IT scheme. An one thing they fail to announce is how they will fund there plans.
Also a other big problem they will face is all these companies will see a chance to gain money for nothing, I mean it the buyer that is redrawing from the contracts an there all those get out clauses , I guaranteed they will walk away from the contracts with hundreds of millions for delivering nothing.
An if you do not think this is the case, one company already demanding 700hundred million for getting fired from the project.
I suspect that once the conservatives are in power they will very quickly relies that cancelling the contracts are impossible or simply cost to much to do so. They will eventually swallow there pride, make some round edges changes, which will change nothing but probably add some more costs to the project but make them appear to do something, which will result in very little change to the current plans.
