A good place to start would be to challenge the oft-repeated claim that there is already such a law. An amendment was certainly passed during the passage of the 2012 Health and Social Care Act to give the Secretary of State for Health a duty to “secure improvement in the prevention, diagnosis and treatment of physical and mental illness”. Since then, members of the government, including the erstwhile Prime Minister David Cameron, have claimed to have “legislated for parity”. But parity of esteem means valuing mental health equally with physical health, and whatever the intention of the amendment’s supporters, the actual wording does not reflect this core principle, since it is possible to technically secure improvement in two things while still disadvantaging one in practice. If there was such a law, the number of patients sent out-of-area – sometimes hundreds of miles away, wouldn’t have more than quadrupled between 2011/12 and 2015/16.
