Greek stocks and bonds fell as a decisive election victory for the Syriza party set up a showdown with creditors over the country's financing needs.
The bonds declined for the first time in four days, having rallied last week as the European Central Bank (ECB) announced a bond-buying programme to boost the Eurozone economy.
Greece's ASE Index of equities dropped 3.2pc, erasing its gain this year. Debt issued by Alpha Bank and Piraeus Bank also slid.
But all three asset classes were above their 2015 lows.
