Greek shares fell on Tuesday before a second round of a presidential vote that could take Athens closer to early elections, derailing EU/IMF-led reforms and raising the risk of another economic setback.

At 0900 GMT, Athens's ATG share index was down 1.9 per cent.

If parliament fails to appoint a president, a general election must be held by early February, potentially bringing in the leftwing Syriza party, which wants to renegotiate the bailout and write off a large part of Greece’s debt.
