A petition that could force a by-election in North Antrim and unseat the current MP Ian Paisley will open later.
In July, MPs voted to suspend Mr Paisley for 30 sitting days over his failure to declare two family holidays paid for by the Sri Lankan government – triggering the recall procedure.
The DUP MP apologised in the Commons but will face a by-election if 10% of his constituents sign the petition.
The recall petition is the first in UK parliamentary history.
This is a fairly recent addition to politics, becoming law under the Recall of MPs Act which came into effect in 2016.
It states that MPs who are convicted of a criminal offence and jailed, convicted of providing false information on allowance claims or barred from the House of Commons for 10 sitting days or longer can lose their seat if there is a successful petition to recall them.
Last month, Mr Paisley received a ban from Westminster of 30 sitting days for breaching parliamentary rules, beginning on 4 September, which triggered the recall procedure.
According to the Electoral Office for Northern Ireland (EONI), the number of people entitled to sign the petition (ie eligible registered voters) is 75,478.
The Recall of MPs Act 2015 says a petition needs 10% of that number in order to trigger a by-election, therefore 7,543 signatures are required.
It would have been 7,547 but last week the Electoral Office said the figure was 7,543 – due to a sweep of the register removing deceased voters and others who were not eligible.
The petition is open for signing for six weeks from 8 August to 19 September from 0900-1700 BST, Monday to Friday.
Opening hours at the designated centres will be extended to 2100 BST on 6 and 13 September.
Letters have already been sent to constituents informing them about the details of the petition.
Anyone wanting to sign it must live in the North Antrim constituency and be 18 years old, or have their 18th birthday before the end of the signing period on 19 September.
But just like in any normal election, anyone wanting to sign it must also be registered to vote in parliamentary elections.
The Electoral Office selected three designated venues which are located at
Legislation allows for up to 10 locations for the petition but the electoral office has opened three, a decision which drew criticism from some political parties.
Voters can also apply to sign by post or proxy. Applications for those must be returned to the Electoral Office by 4 September.
The Chief Electoral Officer, Virginia McVea, said there had been a change in the law in relation to the postal application so anyone who chooses not to attend in person will be able to apply for the postal option and if their details are verified, can receive it within six weeks.
Applications can be downloaded at eoni.org.uk.
There are two help lines for constituents who have queries about the process.
They are 02890446600 and 02890446668.
If the number of signatures reaches or surpasses 7,543 it will trigger a by-election and Mr Paisley will lose his seat.
There would be nothing to stop him from standing in the by-election, however, and he has already indicated that he would do so.
He has been the MP for North Antrim since 2010.
