After months of campaigning, polls have finally opened in the referendum on Britain's membership of the European Union.
British people started casting their ballots at 7am this morning in the historic in/out vote.
Polling booths will stay open until 10pm tonight. Counting begins as soon as the polls close, with a result expected in the early hours of tomorrow morning.
The most recent opinion polls have shown the 'Leave' and 'Remain' sides neck-and-neck.
Torrential rain has swamped parts of south-east England and London, but some of the key campaigners have already been out to cast their votes in the capital:

UK newspapers have also been reflecting on the campaign, and in some cases coming out in favour of a 'Leave' or 'Remain' vote:

Elsewhere, the German tabloid Bild said it will acknowledge the controversial 'Wembley goal' from the 1966 World Cup final if England votes to stay in the EU.
