Throughout my career, I have lived by the principles of personal honor and professional integrity.

What I'm trying to do is teach people how to actually get individuals in organizations to do the kinds of things to make a difference. It starts with not just studying the mechanics but really understanding how people operate.

Our bureaucracy had excelled at compartmentalizing intelligence - we had a 'need to know' system - but by 2004, it was impossible to foresee what elements of our organization would and would not need to know a given piece of information.

In our society, I see public media as a lever. It pushes people by elevating them and their sights. It brings them into more thinking and understanding, and it brings us together.

I deeply regret that those with the authority and responsibility to deal appropriately with Brendan Smyth failed to do so, with tragic and painful consequences for those children he so cruelly abused.

I believe that no man who holds a leader's position should ever accept favors from either side. He is then committed to show favors. A leader must stand alone.

Our MPs will take decisions on how they're voting on a day-to-day basis. But I'm the leader of the party, and in terms of our overall strategy and how we vote on key issues, then ultimately, those decisions will be mine.

If you hang around political talkers or strategists much, you’re likely to hear a lot about authenticity. This is supposed to be the golden currency which we all look for in our leaders."
