Today, a campaign is being launched to urge the Government to end this historic inequality once and for all. The aim is improve access to treatment, reduce waiting times for appointments and encourage an understanding that poor mental health can have just as devastating an impact on an individual’s life as a physical ailment. But this must be more than about equality of resources. After all, parity could be achieved by reducing spending on physical health care. But there are cost consequences; and simply demanding more money for one sector without recognising the impact on another such as cancer care is not feasible without wider NHS reform.
