Greek negotiators are in Brussels to explore the "scope for convergence" with the country's creditors, following days of acrimony over rival reform proposals for a deal that will unlock Greece's last remaining bailout funds.

Government spokesman Gabriel Sakellaridis said Monday that Greece considers the 47-page document delivered by Prime Minister Alexis Tsipras during a visit to Brussels last week to be the basis for a deal.

The institutions overseeing Greece's bailout — the European Central Bank, International Monetary Fund and European Commission — have issued their proposals, but Tsipras rejected them as unacceptable.

Sakellaridis also said the government was not considering elections, an option raised by some ministers if a solution cannot be found.

Meanwhile, Greek Finance Minister Yanis Varoufakis is having talks with German counterpart Wolfgang Schaeuble in Berlin.
