The Swiss parliament rejected an exemption for the transfer of arms to Ukraine on June 1. The majority of members of the Swiss National Council voted against the proposal that had been drafted by the security policy committee of the country's larger parliamentary chamber. The Swiss Federal Assembly is made up of the National Council and the smaller Council of States. The "Lex Ukraine" would have allowed other states to deliver Swiss-made war materiel to Ukraine. The laws of neutral Switzerland prohibit support for countries involved in acts of war. Switzerland has therefore so far refused to give Germany permission to pass along Swiss ammunition, purchased years ago for the German Leopard tank, to Ukraine.
