The petition asking the British government to revoke article 50 and reconsider its plan to exit the European Union passed 6m signatures a day and a half after Britain was meant to have left the European Union.
The number of signatories passed the 5m mark the previous Sunday, making it the most popular petition to have been submitted to the parliament website.
The previous highest total of 4,150,260 was for a 2016 petition calling for a second referendum should the initial poll not provide a definitive enough result.
The woman behind the petition, Margaret Georgiadou, said she had received death threats.
The EU27 expect her to ask for a longer delay or accept a no-deal Brexit two days later, on 12 April.
Some said crashes on the site since the petition launched were a plot to prevent further signatures.
Others claimed that a small proportion of signatures from overseas IP addresses – including one from North Korea – meant the petition had been hijacked by bots. »
