Greece's main opposition New Democracy party will vote to choose a new leader in an election that could see the rise of a prominent political family member.

Dora Bakoyannis, a former mayor of Athens, is seeking to become leader of the same centre-right party that brought her father, former prime minister Konstantinos Mytsotakisto, to power.

The rise of Bakoyannis' family mirrors that of George Papandreou, Greece's new socialist prime minister, and the third Greek leader to bear the Papandreou name.

As Al Jazeera's Barnaby Phillips reports, the constant stream of familiar family names is causing some younger voters to question their leaders' hold on Greek politics.
