Danny Boyle, Sir Ian McKellen, and Sam Allardyce are along high profile figures to have signed an open letter calling for equality for funding for physical and mental health treatment.

The open letter, which has now been signed by more than 200 people, calls for the government to increase "investment into the provision of mental health services".

The letter highlights 10 major concerns over inadequate mental health care, including the lack of access to treatment, long waiting times, inadequate crisis care, use of police cells and the 20-year gap in life expectancy between those with mental health problems and the rest of the population.

It also notes the high cost of mental ill health to individuals and their families as well as the to the economy as a whole.
