An online parliament petition asking the government to remain in the EU and revoke Article 50 -- the clause of the EU treaty under which Britain is leaving -- has been taken down after receiving 1 million signatures in a day.

The website crashed Thursday after receiving an overwhelming number of visitors.

The petition received more than a quarter of a million signatures shortly after it was put online Wednesday.

British parliament's petition committee said on Twitter the petition saw "the highest the site has ever had to deal with."

"The government repeatedly claims exiting the EU is 'the will of the people.' We need to put a stop to this claim by proving the strength of public support now, for remaining in the EU. A People's Vote may not happen — so vote now," petition creator Margaret Anne Georgiadou said.

"Revoke Article 50" was trending on Twitter in the U.K. and worldwide on Thursday, with users also sharing links to the petition.

The British Parliament considers all petitions for debate that get more than 100,000 signatures.
