Workers/Living/Retir ement France

For French workers take note if you are nearing retirement. I am living in France and have worked both in Britain and France and nearing retirement. I have just been told that I must retire before 31/12/2020 otherwise my French pension will be lower. This is because Brexit, if I retire later I will lose the extra bonus points the French award to people from other EU countries who have worked in the EU. However my basic French pension will not be touched.
