If Robin Cook's proposals to reform the parliamentary working week do reduce the anti-social hours and punishing schedules at Westminster, then they are to be welcomed, not least because they might improve MP's mental health.

Our own research of more than 100 MPs suggested that nine out of ten found their job either very or fairly stressful, and a total of around 30 members had themselves experienced a diagnosed mental health problem.

The workload of MPs not only puts a strain on them but their families, and is not a matter for either complacency or humour. MPs make the laws that affect all our lives, and whatever party they represent they need to enjoy good mental health and be free of undue stress.

Reforming the working hours of Parliament is a step in the right direction, but more needs to be done.
