In a speech on Thursday in the German federal parliament in Berlin, Merz says that European companies need a "sufficiently broad and deep European capital market, so that they can more easily and quickly find financing".

Merz refers, among other things, to the former ECB chief Mario Draghi's report from last year, which pointed out that Europe is falling behind in the competition.
