Prior to Brexit, the language of choice for the EU was English. The French and Germans could (and did) argue as much as they liked but English is the international language of choice.
Post Brexit, English may still be preferable but both the French and Germans have a better case to put their language forward.
Brexit is ludicrous on so many levels and it'll take decades to repair the damage caused in the last couple of years.
Still at least I found the wife's Christmas present, found in England at a decent price as a direct result of Brexit.
