A pro-European Union activist group in the U.K. sent an urgent “SOS” to leaders on the continent with a massive projection on the White Cliffs of Dover.

Photos and video of the 3,000-square-meter projection, which read “SOS” in the colors of the EU flag, was posted to Twitter by the “Led By Donkeys” group.

“Dear Emmanuel Macron and Angela Merkel, opportunists from the hard right want Britain to crash out of Europe, even though a majority now wants to stay,” the group wrote. “We think the people should decide what happens next. But please give us more time.”

The projection, which faced France, backed calls to let U.K. voters have the final say on Brexit, the decision by the U.K. to leave the EU. A movement for another public vote on leaving the EU gained more traction last month after an online petition gained nearly 6 million signatures.

The photo, which was retweeted by thousands of Twitter users, caught the attention of Guy Verhofstadt, the Brexit coordinator for the European Parliament.

“Quite something to see the White Cliffs of Dover turn blue,” he tweeted in response. “But the European project is much more than a lifebuoy. It's our rock on which we have to build our future, especially in turbulent times.”

Led By Donkeys has spread its message by erecting billboards of “historic Brexit pronouncements” from British lawmakers' tweets.

During Prime Minister Theresa May’s recent trip to Brussels for continued Brexit negotiations, the group put up a billboard of her tweet, reading: “It’s in Britain’s national interest to remain in the European Union," according to the Evening Standard.

The projection on the White Cliffs of Dover comes ahead of continued cross-party talks, the British government’s new approach to Brexit. May and opposition leader Jeremy Corbyn met Wednesday in an effort to end a deadlock over the U.K.’s “divorce deal” to leave the EU.

The House of Commons on Wednesday voted in favor of a bill to avoid a no-deal Brexit and force May to ask the EU for another delay from its current departure deadline of April 12.
