With the polls closed in South Korea's elections, an exit poll by three of the country's main television stations suggests the ruling Saenuri Party's Park Geun-hye has a slim lead.

Combined figures from the networks released after polls closed give her 50.1% of the vote, in a race where turn-out has been very high and economic and social welfare issues have dominated.
