Errors and weaknesses in healthcare will inevitably happen, but there can be no reason to tolerate serious incidents on this scale - particularly those involving unexpected deaths and fatal self-harm. In government, I was determined to end the historic injustice against those suffering mental ill health. It is time for people of every stripe to pull together to complete the job.
While making PrEP available is ultimately a decision for NHS England, rather than for politicians, I hope they will take steps to make PrEP available to people considered to be at high risk of catching the virus, without further delay. This could have an enormous impact on the lives of countless numbers of people in high-risk groups and be a vast improvement on our current approach, which wastes NHS resources and has let down far too many people.
I know from personal experience just how vital good mental health care is for families across the UK. One in four people experience poor mental health at some time in their lives and this means that everyone knows somebody who has had a mental health problem. Yet for far too long our society has not prioritised mental health care. For decades, it has been at the back of the queue for funding and the front of the queue for cuts.
The truth is that there is outrageous discrimination at the heart of the NHS. If you have suspected cancer you have a right to see a specialist within two weeks - and rightly so. But if you are a teenager with an eating disorder - a condition which can kill - you have no such right. It's impossible to justify that.
As I write this article, I am on the Eurostar from London St Pancras to Brussels. You might think this a strange diversion in the final week of my campaign to become leader of the Liberal Democrats. But today's trip is at the very heart of why I want to lead our party. Because whether we are a party of eight MPs or 208, we cannot hope to address so many of the challenges we face as a society on our own. The great threats of the coming decade - global climate change, mass migration, international economic upheaval, and a deteriorating security situation - are international challenges, requiring international solutions.
In the Liberal Democrats, it's not the leader who sets policy, it's the membership. But I reckon it's not unreasonable for leadership candidates to set out their own views, and to call for a rethink where they believe the party's got it wrong on any particular policy. And I think we have got it wrong on fracking.
The Lib Dems seem quite a tough lot. While it is impossible to ignore the gravity of the electoral crisis which has clobbered the party at all levels since Nick Clegg led it into coalition with the Tories in 2010, Britain without a Liberal party would be an alien place... So what is going on: and will it make any difference who wins?
There can be no other area of public policy, with the exception of the related issue of drugs reform, where establishment politicians so readily bang the drum for the exact opposite of any evidence-based solution. Our prisons clearly fail to rehabilitate: half of those released reoffend within a year, including six in ten of those on sentences of less than twelve months. Liberal Democrats must lead the call for drastic and urgent action to reduce crime, protect victims more effectively, help criminals turn their lives around and protect taxpayers money: we must push for a Ministry of Justice target to halve the prison population by 2025.
Norman Lamb is the future. Do not be deceived by his age, or his general weary look that can be found on any remaining member of the Liberal Democrat party, Norman Lamb is a true social visionary. With the departure of Nick Clegg, another bastion of social reform, the top spot in the Lib Dem camp is now vacant.
This has probably been the first ever election where mental health has started to be recognised as the crucial issue it is for millions of people across the country. It has been fantastic to see the focus here on the Huffington Post on mental health. But we have to make sure that this apparent consensus leads to action.
With mental illness costing our economy over £100 billion pounds a year and millions of lives put on hold because there isn't the right support, we desperately need to accelerate the pace of change. That's why mental health must become a key issue in this election campaign, and I'm proud to be able to say that the Lib Dems have thrown down the gauntlet. To keep on delivering a stronger economy and a fairer society, mental health has to take centre stage.
