Polls have opened in Greece in the second general election in less than two months with the ruling conservative party strong favourites to win a wide majority.

The 55-year-old conservative leader Kyriakos Mitsotakis is eyeing a second four-year term as prime minister after his New Democracy party won by a huge margin in May, but fell short of gaining enough parliamentary seats to form a government.
