What are our ministers’ signature achievements?

One of the great things about Lib Dem Conference is that you can ask all kinds of questions to different people in public and they have to answer.

Here’s my question to the Chief Whips of the Lords and Commons Parliamentary Parties:

For each Minister based in the Commons/Lords, what do they consider to be their ‘signature  achievement’ – the achievement they have made as a minister that most clearly demonstrates the difference that Liberal Democrats – and they – are making in Government?

I look forward to their answers!
