Is the EU trying to scare the UK into staying in?

In the UK, it would be "extremely difficult politically to backtrack on the referendum result", said Agata Gostynska-Jakubowska, a research fellow at the London-based Centre for European Reform. The only possibility would be an early election, she told EUobserver, adding that such a scenario was “politically difficult to imagine”.

..."It is difficult to win an election with that," Gostynska-Jakubowska noted. "People are still not sympathetic to the EU." In addition, she said, a two-thirds majority in the House of Commons is needed to call an election, so "it would not only be the Conservative Party's call".
