Like Margaret Thatcher, former Prime Minister of the UK, Brundtland has a reputation for toughness. She thinks that, to be a leader, you need to be forceful and that no-one thinks twice when men display these leadership qualities.

 "I don't think you can be a leader without being forceful. If you don't have a determination, if you don't have a perspective and a direction in your mind about what is your vision, what do you want to try to get support to be able to do, then you are not a leader. So you will not find women leaders who are successful who are not able to speak up, who are not able to tell what they want and why. And the thing is that when men do this, nobody is surprised that they are forceful. But when they see a woman in Norway and a woman in England doing it, they take note - but the main fact is we were both leaders, and we were women but you cannot lead without leading."
