The function of president in France is one of significant symbolic value; it can't be compared with that of prime minister or cabinet member. Everything you do, everything you say - but also what you don't say - suddenly has meaning. That might sound quite formidable or even stressful, but I think it is a product of the history of this role.

I believe we find ourselves in a period of radical transformation. Regardless of whether it is digitalization, the environment or terrorism. We can be successful in this new world. We have the necessary willingness. The French are inventive and innovative. But we need to finally pick ourselves up.

Many European parties, including the conventional parties in France, no longer have the ability to keep people together. And in terms of the coalition government, I am convinced that Angela Merkel has the necessary will and ambition. I want to be very cautious with my statements about her coalition negotiations, but support for Europe is part of the DNA of both the Greens and the Free Democratic Party. I was very pleased that the heads of both parties spoke out positively about the European project.

Our political system encourages that. We don't have proportional representation. There's little renewal in our political class and it's always the same faces. There's also a lack of morals - it's one affair after the other. A system like that cannot be successful.

Look at me, the Front National got many more votes than the Alternative for Germany. Marine Le Pen ended up with 34 percent of the vote, 34 percent! I defended Europe, an open society and all my values. The Front National has been significantly weakened. In the debates, you don't hear anything from them anymore - because we engaged them in battle. Now is the time to be bold! The only answer to the Alternative for Germany is courage and ambition.

I am not from the political or banking elite. I am a child of the middle class far from Paris. And if someone had told me that success is bad or if they had placed hurdles in my path, I wouldn't be where I am today. I want it to be possible for young people in our country to be successful - whether they want to find that success in the family, as an artist or by founding a company.

The story of my grandmother is that of a French woman from the provinces who through her perseverance and thirst for knowledge worked her way up to become the head of a school. She belonged to a generation that didn't travel much. But she believed in Europe and she wanted Europe. And she read a lot - she knew mythology, literature and the classics very well. She passed that on to me, along with the conviction that you can earn your own position in society.
