Everald Warmington has resigned as Member of Parliament for South West St Catherine.
Speaker of the House of Representatives Delroy Chuck made the announcement in the House at the start of the sittings today.
In a letter read by Chuck, Warmington said he resigned because he felt he had offended section 40(2) of the Constitution.
That section of the Constitution speaks to eligibility for membership to the House of Representatives and Senate.
On February 1, The Gleaner reported that the fiery government member of parliament (MP), could be the next person forced to leave the House of Representatives in the long-standing battle over dual citizenship.
The Gleaner had examined documentation, which appeared to have proven that Warmington was a United States citizen at the time of his nomination for the 2007 general election.
Warmington subsequently renounced his US citizenship, but that came during the squabble over other members of the House who had sworn allegiance to a foreign state.
"It is an issue that the party is aware of and one which we want to settle before it becomes a court matter," a senior Jamaica Labour Party (JLP) source told The Gleaner.
"What is on the table is for Warmington to resign and allow the prime minister to call a by-election in the constituency where he is sure to be re-elected," the source said.
Warmington won the South West St Catherine seat in the 2007 general election, polling 10,488 votes to the People's National Party's (PNP) Dr Dennis Jones, who grabbed 7,244 votes.
So far, members of the PNP have successfully challenged four members of the governing party who held dual citizenship at the time of nomination - Daryl Vaz, Michael Stern, Shahine Robinson, and Gregory Mair.
All four were subsequently re-elected in by-elections.
The JLP has moved after two sitting Opposition MPs - Ian Hayles and Sharon Hay-Webster - but these challenges are still to be settled in the court.
As Chuck read Warmington's letter some government members shouted "what about Sharon, what about Hayles".
Meanwhile, when contacted by The Gleaner in February, Warmington refused to entertain questions on the issue.
"If you want to call me, then call me about something substantial, don't call me about those petty stuff," declared the junior minister for water and housing.
He added: "In the middle of the day, I am doing the Government's work. I can't discuss stupid rumours or discussions ... . I don't want you to call me about certain nonsense."
