They will then be assessed at a broader meeting of technical-level teams from Greece and the lenders in Brussels on Thursday, Greek government officials said. Despite the scepticism of lenders, Greece's government is hoping an "interim" deal can be struck before a May 12 payment of 750 million euros (£537.3 million) to the IMF that Greek officials have suggested could be difficult to pull off without more aid. The lenders have said a partial disbursement of a pending aid tranche is not possible until Greece has presented a full list of reforms but the government is hoping an initial deal will prompt the European Central Bank to loosen restrictions that prevent Greek banks from buying more Treasury bills. They must also decide." The ECB, which has kept Greek banks on a tight leash while talks with lenders continue, raised the cap on emergency liquidity assistance available for Greek banks by 1.4 billion euros to 76.9 billion euros, a banking source told Reuters on Wednesday.
