Creditors offer Greece six-month bailout reprieve as Tsipras weighs response

Deal may also include up to a18bn in rescue funds, and later debt relief, but EU officials stress Greek prime minister must make concessions

Greece's international creditors are aiming to strike a deal to stop Athens defaulting on its debt and possibly tumbling out of the euro by extending its bailout by six months and supplying up to a18bn (12.9bn) in rescue funds.

The negotiators representing Greece's lenders are also proposing to pledge debt relief for the austerity-battered country - but officials stressed that a breakthrough hinged on a positive response from the Greek prime minister, Alexis Tsipras.
