Parliament's petitions website is once again accepting submissions after being closed for the general election.
Petitions that gain 10,000 signatures will receive a government response, while those with 100,000 names will be considered for a debate in Parliament.
During the 2017-19 Tory government, 28,102 petitions were submitted to the site, up from 10,950 in 2015-17.
A petition to remain in the EU received the highest number of signatures so far - 6,103,056 - in March 2019.
Other notable petitions including one urging Prime Minister Boris Johnson not to suspend Parliament in 2019, signed by 1.7m people,.
Another petition, to stop US President Donald Trump from making a State visit to the UK in 2017, was signed by 1.8m people.
In the last Parliament, 456 petitions received a response from the government and 74 petitions were debated in the House of Commons.
Since the website launched in 2015, more than 23 million people have used the site.
Catherine McKinnell, the new chairwoman of the Petitions Committee, which has reformed following December's general election, said she was looking forward to "supporting the public to raise awareness of their causes in Parliament and help bring about real change to communities across the UK".
The website had been unable to accept new petitions since November 2019, due to rules around select committees disbanding for general elections.
