With just two days to go before the referendum on European Union membership, Britain's newspapers have publicly come out on their chosen sides, hoping to influence the debate.

The Financial Times, UK's leading financial newspaper, urged its readers to keep Britain within the 28-member bloc, saying quote, "a vote to withdraw would be irrevocable, a grievous blow to the post-1945 liberal world order."

The Guardian backed Britain remaining in the European Union, telling its readers that they should keep connected and inclusive, not angry and isolated. The newspaper also urged Britons to vote against a divided nation that turns inwards.

The Sun, the nation's biggest-selling newspaper, urged its readers to vote leave and set the UK free from dictatorial Brussels. The tabloid has a circulation of 1.7 million. Polls show many of its readers already back a Brexit.
