 The end of the cabinet was finally brought about by the "Londoner Ultimatum".By late April/early May there were rumours that the Allies were about to present a new payments schedule in connection with threats of new sanctions (as happened on 5 May).On 4 May, despite an uprising in Upper Silesia that had erupted the previous day, the cabinet decided to resign after the parties were unable to agree on whether to present the Allies with a new German proposal on reparations.
