Britain urges Germany to permit supply of tanks to UkraineLONDON, Jan 16 (Reuters) - Britain on Monday urged Germany to permit the supply of Leopard tanks to Ukraine, stressing that it could unlock support from other nations and Berlin would not be acting alone if it supplied its own tanks."All of this currently relies on the German government's decisions - not only whether the Germans will supply their own Leopards, but whether or not they'll give permissions to others.German Defence Minister Christine Lambrecht resigned on Monday as her government came under rising pressure to let allies send Ukraine heavy tanks, at the start of what is likely to be a pivotal week for Western plans to further arm Kyiv.Germany has resisted such a move so far, saying Western tanks should only be supplied to Ukraine if there is agreement among Kyiv's main allies, particularly the United States.He said the scale of support would be evident at a meeting of Ukraine's allies in Ramstein in Germany on Friday."
