After years of piecemeal reform the current welfare system is complex and unfair.

[Andrea] Leadsom has compassion ... a real steel and a real determination and that velvet glove of compassion that she really cares about people.

I think that the status that you have in life should be reflected in official documents. If you are married, fine, if you are living with someone, fine, if you are single, fine. We don't want to tell people how to live their lives.

If Britain is to have a stable, affordable pension system, people need to work longer, but we will reward their hard work with a decent state pension that will enable them to enjoy quality of life in their retirement.

My view is pensioners don't have the one option that people of working age have. They can't really increase their income, because they are no longer able to work.

There is nothing people can throw at me to say: Do this, do that.

In many ways Scotland will benefit more than other parts of the UK when universal credit comes in. A larger percentage of people will see an increase in their income through moving into work or taking on more hours.
