Greeks will be heading to the polls on Sunday to elect a new government.
The vote was called after left-wing opposition Syriza and other lawmakers blocked the vote for a new president, leading the country to a snap election. Front-runner at the moment is Alexis Tsipras' Syriza, ahead of New Democracy, led by Prime Minister Antonis Samaras. But it's not likely to be a two-horse race – or anything that straightforward.
The Greek parliament has 300 seats – that's the easy bit. Under Greece's electoral law, the party with the most votes automatically gets 50 seats. The other 250 seats are handed out according to the share of the vote – so the leading party can still get more seats. Only political parties that have got at least 3 percent of the overall vote can get a seat in the parliament.
