The big achievement of Tsipras's proposal is to sow division - Münchau

The financial markets seemed to have made up their mind that a deal will happen. But beware the many landmines on the path to a deal. Of those, only the first has been sidestepped with Mr Tsipras's offer. What he is now proposing is, economically, not fundamentally different from what he, and the Greek electorate, rejected in Sunday's referendum -- but it works politically for him. The phase-in period of some of the harder measures is longer. And if there is a deal, there will have to be an explicit reference to debt relief this time. The IMF insists on it. And even Donald Tusk, the president of the European Council, says so. This is an important development, but it is not clear that all creditors will, or can, agree.

By tomorrow, the technical people and the finance ministers will need to discuss whether the Greek numbers add up. The answer is almost certainly no, not least because of the rapid deterioration of the country's economy.
