The Mind and Soul website, which is one of the best things on the internet. has produced a helpful summary of all the mental health proposals of the main parties. There are quotes from each main leader, a list of what's in their manifesto, and what isn't, and it all looks pretty fair and balanced.
It's been put together by Will van der Hart, who concludes thus:
However you choose to vote in the General Election, enjoy the democratic freedom that empowers you. Pray for those who are in leadership and carry the responsibility for seeing a huge improvement in the provision of mental health services within the UK. Also pray for those in other nations and our own, who through discrimination, repression and stigmatisation are denied their basic rights becuase of mental ill-health.
