Nationalist MP Ryan Callus has offered his parliamentary seat to the new PN leader if he or she is not already in the House.

In a post on Facebook, Callus said that he had "given careful thought to the needs of our Party and our country. I have spoken at length with colleagues in our Parliamentary Group, as well as with our activists and grassroots supporters."

Callus did not mention any names but it is likely that he is referring to Roberta Metsola, who is touted as a possible replacement for Bernard Grech, who resigned as PN leader on Tuesday.

"It is clear to me, and to most of my colleagues, that the Party urgently needs unity and a renewed consensus. It has also become evident that the person best positioned to bring this unity and enjoys the broad electoral appeal we need to win the next election might not be a Member of the Maltese Parliament," he said.

"For this reason, and with a deep sense of responsibility, I declare my readiness to relinquish my seat in Parliament should she or he be elected as the next leader of our Party by our members. This will ensure a seamless and effective transition into Malta's Parliament," he said..

Callus said he has carefully "considered the sentiments of my constituents and the pressing needs of both our Party and our country. This decision was not made lightly; it reflects my deep respect for the will of the people and a commitment to the best interests of our nation and our Party."

Callus said he believes that new leadership can infuse the "fresh energy and vision we need to build a brighter future together. I wholeheartedly pledge my loyalty and support to whoever our Party members choose to lead us forward."

"I remain fully committed to serving our country in any way I can, and to supporting the growth and success of the Nationalist Party. Most importantly, I will always stand by the Malta that I love."
