PN leader Alex Borg told supporters on Monday that the party had "started a revolution" and opened a new chapter for Malta in the first 100 days of his leadership.
Addressing a mass rally in front of the PN headquarters in Pietà, Borg described the PN as "a winning party", as supporters gathered to mark the milestone.
The rally brought to a close a seven-day "Christmas village" at Dar Ċentrali, which included a televised fundraising marathon on Sunday that raised more than €730,000. In total, Borg said, over €1 million had been collected in recent days - a record sum he described as a "certificate of trust" from the public.
Supporters welcomed Borg with chants of "Nazzjonalisti, Nazzjonalisti", waving placards reading "This is the moment" and "Alex Borg", as fireworks were set off from the headquarters' roof ahead of his speech.
Earlier in the day, the PN submitted its long-overdue audited financial statements for the years 2021 to 2024 to the Electoral Commission. The statements show that the party's total liabilities stand at €11.7 million.
Borg said the publication of the accounts was a key promise of his leadership campaign.
"I made many promises during the campaign that the PL said we could not achieve," Borg said. "Today marks 100 days of my leadership, and all that I promised has been achieved."
Referring to the financial statements, he said the move was necessary to ensure credibility and restore public trust, adding that the PN was demonstrating it could be credible even while in Opposition.
Borg also highlighted what he described as growing public engagement with the party. Citing a broadcasting survey, he claimed that NET Television had, for the first time, become the most-watched station in Malta, which he said reflected its role as "the voice of the people".

He also referred to €15,000 raised through a crowdfunding campaign to support the party's podcast, mocking the PL's plans to launch a similar initiative.
"We lead, and they follow," Borg told a cheering crowd.
In a further announcement, Borg revealed that the PN had gained 3,000 new paid-up members in the first 100 days of his leadership.
While celebrating the achievements, Borg cautioned that much work still lay ahead.
"No matter how long the road is or how big the challenge feels, we see hope at the end of the road," he said. "These 100 days have shown that when we organise ourselves, work together, trust the people and bring energy to the party, we can bring about change."
