On the 25th anniversary of the September 11 attacks, UK Prime Minister Burnham issued a formal statement reflecting on the tragedy and the ongoing geopolitical landscape. The Prime Minister underscored the enduring alliance between the United Kingdom and the United States, framing the relationship as a cornerstone for global security and the protection of shared values.

In his remarks, Burnham utilized the phrase that terror "still knocks at the door of democracy," a sentiment intended to highlight that the threat of extremism remains a persistent challenge for modern nations. The statement focused on honoring the victims of the 2001 attacks while signaling a resolve to maintain international cooperation in counter-terrorism efforts. While the Prime Minister’s message was largely commemorative, it also served as a reminder of the evolving nature of security threats since the events of 2001. The address did not detail specific policy changes or new security initiatives, focusing instead on the symbolic importance of the anniversary and the historical bond between the two nations.
