Germany calls May's Brexit speech 'disappointing'
"I found the speech disappointing," Gabriel told reporters in the northern German city of Woelfenbuettel.
"We heard nothing concrete. It is time for the government of Great Britain to clearly state under what conditions it wants to leave the European Union."
May set out a plan on Friday to retain full access to the EU's single market for two years after Brexit to try to reassure business and reset the tone of stalled negotiations with Brussels.
