Portugal's centre-right government has won an election that was a test of its tough austerity stance, but its failure to win a majority in parliament raises the prospect of political uncertainty.

However, a minority government could unnerve investors in the Portugal where not one minority administration has survived a full term since the 1974 overthrow of the fascist regime installed by dictator Antonio Salazar.
