I wouldn't be in parliament if it wasn't for the inspiration of my dad. At his best, he was inspiring, charismatic - and hugely idealistic. He inspired me into politics and public service.

Today, alcohol harm costs our country £21billion a year. It's the third biggest public health risk after obesity and smoking. It costs the NHS alone £3.5billion.
