Battle between Macron and Le Pen as France votes for its next president
A great deal of attention will be placed on the turnout this time around, with plenty of speculation that voters will stay away because they don't particularly like either candidate.
FranceFrance is voting in a presidential run-off election between incumbent Emmanuel Macron and far-right politician Marine Le Pen, reports Sky News.
Mr Macron, the sitting president, is pitched against Ms Le Pen, leader of the Rassemblement National party, and both were photographed casting their votes on Sunday.
They are candidates who could hardly bring a greater contrast - Mr Macron from the centre of politics; Ms Le Pen with more radical opinions.
A man whose bedrock of support lies in cities and big towns against a woman who has relied on rural areas and small towns for much of her backing.
Polling stations opened at 8am local time (7am UK time) and will close at 7pm, although some centres in big cities are allowed to remain open for another hour until 8pm.
