Schroeder isn't far-right, no. Schroeder was a bit like a softer version of what pre-Obama era Trump was expected to be like as a politician (i.e. when he was still expected to run as a Democrat). He openly has financial ties to Gazprom these days (or at least before the invasion of Ukraine - haven't heard much from him since) and seems to have spent most of his time after being chancellor schmoozing with oligarchs. Of course none of that demonstrates any corruption because his close ties to Russian money and his pro-Russian economical stance as a chancellor are entirely separate and there's no reason to suspect any conflict of interest. /s
