Sir – The MP for the Witney constituency of Oxfordshire assured us that “the health service will be safe in our hands”.

I believe he (David Cameron) worked for the present Health Secretary in opposition and yet, now, every professional health organisation in the country appears to be deeply critical of the changes being proposed for our National Health Service.

Naturally people — and especially those with health problems in their families, are concerned at such a stand-off.

I hope that Members of Parliament in the county who support the proposed changes will make themselves publicly available for discussions with their constituents and seek to justify their apparently new beliefs.
