# UK political discourse on Brexit and foreign interference > Live situation record from CLSTR: https://clstr.news/situations/uk-political-discourse-on-brexit-and-foreign-interference > Updated: 2026-10-13T12:29:40.000Z. Sources: 248. Developments: 3. Prime Minister Andy Burnham has linked various national challenges to the United Kingdom’s departure from the European Union. In late September, Burnham attributed a surge in illegal migrant crossings via the English Channel to Brexit, stating it caused a “loss of collaboration with neighbours” that hindered cooperative systems. By mid-October, the Prime Minister expanded on the implications of Brexit by stating it was ‘clear’ that Russia interfered in the 2016 referendum. Speaking on the podcast ‘The Rest Is Politics’, Burnham became the first sitting UK leader to publicly confirm this interference, noting that after assuming office this summer, he requested a briefing and received a ‘clear answer’ that meddling had occurred. While confirming the interference, Burnham has not yet specified the exact source of his information, the specific methods used by Moscow, or provided supporting evidence. Burnham connected these findings to broader foreign disinformation campaigns currently impacting political landscapes in Germany and France. Following these remarks, MI5 Director Ken McCallum confirmed that Russian state-controlled media, including RT and Sputnik, engaged in “strong interference efforts” around the time of the vote. McCallum also identified a second front of interference involving trolls and bots on social media platforms like X, though he cautioned against exaggerating the impact on the final outcome. The Prime Minister’s comments have reignited debate regarding the legitimacy of the Brexit process. Burnham has suggested the current post-Brexit arrangement is inadequate and has signaled a potential openness to discussing a future referendum on rejoining the EU, noting that a new pact with the EU could add over £10 billion annually to the economy by 2040. ## Claims - British Prime Minister Andy Burnham confirmed that Russian interference occurred during the 2016 Brexit referendum.
