Ian Paisley's held on to his North Antrim seat after the British parliament's first ever recall petition.
The MP has been caught up in an expenses scandal and was banned from the House of Commons for 30 days.
It's after he failed to declare two holidays paid for by the Sri Lankan government.
He would've had to fight a by-election if ten percent of voters in his constituency had signed the petition.
Northern Ireland's Chief Electoral Officer Virginia McVeigh announced the outcome overnight saying the percentage of electors who validly signed the petition was 9.4%

Meanwhile Northern Ireland's Democratic Unionist Party (DUP) says he's been re-admitted to it.
He was suspended from the DUP in July over the expenses scandal.
The DUP said in a statement: "The internal processes surrounding these matters have been completed.
"On Tuesday 18th September Mr Paisley was readmitted to membership of the party following a suspension of 57 days and upon re-admission he is subject to a number of conditions including a ban on holding office within the party for 12 months."
