Ed Conway, the economic editor of Sky News cites a source in Greek negotiations and says talks are "Not going well... Greeks backtracking significantly. Measures not credible. Don't know if there'll be deal."

The latest proposal from the Troika has also been rejected. They offered a $17.3 billion proposal today and right away Tsipras was talking blackmail and whatnot so news of the rejections shouldn't come as a big surprise.

The Troika is trying to push through a short-term extension because time is on their side. Tsipras is strong politically right now but in 5 months he might be weaker and that's what the Troika is betting on. Tsipras knows he has a fairly strong hand right now and wants to negotiate a longer-term deal.

Syriza is pondering 'many' scenarios and refuses to recycle the vicious circle of austerity, according to the Guardian.
