Reform UK's Head of Policy Zia Yusuf has attributed the party's dramatic rise in opinion polls to widespread public backing for its stance on energy and immigration.Speaking to GB News, Mr Yusuf claimed the party now enjoys support from approximately one third of British voters."The reason why Reform has surged in the polls and why we command the support of almost a third of the country, of the electorate, is because a third of the country agree that if we don't change our ways as a country with regards to energy policy," he told the broadcaster.Mr Yusuf launched a scathing attack on the Government's environmental targets, describing the commitment to net zero as a "mad religious obsession" that is damaging the nation.He also took aim at current border policy, characterising it as "insane mass untrammelled immigration and an open borders policy."The Reform UK official painted a stark picture of those crossing the Channel, claiming "tens of thousands of military aged men turn up on our beaches uninvited from countries that hate us."Mr Yusuf warned there was no indication of any shift in approach, stating: "And there's no sign of any of that changing. Of course, not only will bad things happen, they are happening."Mr Yusuf invoked President Trump's stated ambitions regarding Greenland to challenge the calibre of British political leadership."President Trump is saying that he wants the United States to take Greenland. He is the president of the United States, and that's what he wants," he said.The policy chief used this example to pose a pointed question about domestic politicians: "When are we going to get British political leaders who will stand up for our interests?"His remarks suggested Britain requires more assertive leadership willing to pursue national interests on the global stage, drawing an implicit contrast with the current American administration's approach.Mr Yusuf argued that the current geopolitical landscape demands a fundamental reassessment of national priorities."Look, it's clear whatever your political views, it is clear that today, in this new world order, economic strength and military might matter more than at any point since World War Two," he stated.The Reform UK figure condemned successive governments' environmental policies in the harshest terms, describing "the insane crushing of British industrial production and capacity at the behest of virtue signalling climate goals" as "one of the most treacherous acts of self-harm ever in this country by the Tories and Labour."He concluded with a rallying cry: "It's time for Britain to rebuild, rearm and compete on the world stage. And that's what Nigel Farage will do for us as Prime Minister."WATCH ABOVE.
