British MPs are slated to debate on Monday a petition signed by over four million people asking for another referendum on the UK's membership of the European Union (EU).
A petition calling for the Government to hold a second poll as the turnout on June 23 was below 75% and fewer than 60% of the vote backed Brexit has received 4.1 million signatures, although it was subject to claims it had been hacked.
The House of Commons' Petitions Committee announced an investigation and later denied its site had been hacked after confirming tens of thousands of signatures were "fraudulently" added.
The petition, which has received the highest number of signatures on the e-petition system, asked for the Government to implement a rule that there should be another referendum on the EU membership question if the vote failed to achieve the two thresholds.
Parliament is obliged to debate any petition that receives over 100,000 signatures.
An official Government response to the campaign said the vote to leave the EU "must be respected" and Brexit preparations must now take place.
British MP from the Scottish National Party (SNP) and member of the Petitions Committee Ian Blackford was to open the debate later in the day.
Monday's debate was symbolic and could not alter the result of the referendum in June.
In the historic referendum on June 23, 52 per cent of the electorate voted in favour of the UK leaving the EU.
The government has said that the choice of the British voters must be respected and it would comply with the democratic decision of the population that supported Brexit back in June.
Prime Minister Teresa May has indicated that she will not activate Article 50 of the Lisbon Treaty -- the mechanism that triggers the process of the UK's withdrawal from the bloc -- before the end of the year.
