It's not hypocrisy to change your mind or change direction as the situation changes.

Unfortunately, it's becoming increasingly obvious that the Tories never planned on following through with their promises in the first place. Their original justification was that the country's finances were so bad they couldn't afford all the things they'd promised. However, now that everyone's mostly forgotten what they originally said and they've deleted it from the internet David Cameron has declared that his policy of closing and crippling the Government services he got elected on the promise of protecting is permanent and has nothing to do with the country's financial state after all.

It can demonstrate a lack of judgement.
