The Prime Minister is urging Oxfordshire County Council to look again at its proposals for £69m of cuts. He says he understands that councils must make further savings but, as an Oxfordshire MP, he says the council should have a re-think.
Oxfordshire and other councils must continue to reform the way they work to become more efficient, both in back-office functions and in front-line service delivery. Further savings do still need to be made, and with councils accounting for a quarter of all public spending they need to continue playing their part in tackling the deficit left by Labour.
The recent Spending Review included a package of measures to support local government, enabling them to streamline their asset base and invest in services.
We have made it possible for councils to sell property assets and use the capital to invest in transforming local services – and ensure further savings. We have introduced council tax flexibilities to help councils with the growing costs of adult social care. And by the end of this Parliament, councils will also keep 100% of local taxes including all £26 billion from business rates.
