The most senior of ministers weighs in

There is concern among opposition parties in Greece that Prime Minister Alexis Tsipras may not be willing to do what it takes to reach a deal with creditors.

New Democracy leader Evangelos Meimarakis has sent two of the parties senior politicians, former ministers Dora Bakoyannis and Costis Hatzidakis, to Brussels to monitor the talks.

"In Brussels to strengthen the national effort," Ms Bakoyannis tweets.

There seems to be a lot of movement on the Greek side towards a deal.

But there may be one obstacle within PM Alexis Tsipras's own party, Syriza.

Panagiotis Lafazanis, the leader of a far-left group within Syriza (and Mr Tspiras' own energy minister) says he may stand in the way.

"We don't want to add a third bailout of tough austerity which will not give any prospect in the country," he said.

He is also quoted by Kathimerini newspaper as saying there were "other options" available.
