PM Andy Burnham meets EU leaders in Brussels to push for closer ties

Fact-check index: 78/100 — The article's core claims—Burnham's diplomatic trip, Cameron's warning, and Williamson's Express criticism—are accurately sourced to the Daily Mail and Express, but some contextual claims about the Remembrance Sunday backlash and the characterization of Cameron's intervention as 'rare' go beyond what the cited sources establish.

• Burnham is meeting European leaders today to press for closer UK-EU ties — Matches Daily Mail: 'the Prime Minister prepares to sell his Brexit betrayal to European leaders today', cited and linked.
• David Cameron, former Conservative PM and committed Remainer, cautioned Burnham against triggering a fresh membership debate — Matches Daily Mail headline ('Cameron tells the PM not to rejoin the EU') and text ('his predecessor, an arch-Remainer, warned against triggering another debate').
• David Williamson in the Express accused Burnham of raising left-wing hopes of EU reconciliation despite Labour's manifesto ruling out single market return — Matches Express subheading almost verbatim: 'PM is promoting leftwing hopes for an EU reconciliation... despite manifesto barring return to single market'.
• The trip follows a Remembrance Sunday address that triggered backlash from Brexit-supporting MPs and commentators — Not established by the two cited sources (Daily Mail, Express); relies on the article's own earlier linked coverage, which is not part of the provided source material for this fact-check.
• This is 'a rare instance of a Remain figure urging restraint on EU engagement rather than pushing for more of it' — Editorial interpretation added by the article; plausible given Cameron's Remainer identity but not a claim made or framed this way in the sources.
• Whether today's talks produce concrete commitments, and whether Cameron's intervention emboldens backbenchers — Forward-looking speculation framed as 'what to watch'; not a factual claim verifiable against current source material.
