Burnham’s casual style faces its toughest test at No 10

Andy Burnham has built a political career on looking like he just stepped off a football terrace. The tracksuit tops, the open collar, the deliberate absence of a tie — it’s not an accident. It’s a brand. But the moment he walks through the door of 10 Downing Street as Prime Minister, that brand runs headlong into one of the oldest dress codes in British public life.

The hoodie that won Greater Manchester

Burnham became Mayor of Greater Manchester in 2017 and was re-elected in 2021 with 67.3 percent of the vote. A significant part of his appeal was that he looked nothing like a Westminster politician. He wore Adidas. He showed up to press conferences in a puffer jacket. He once conducted an entire media round after a 10K run, still in his running gear. Local voters loved it. It said: I’m one of you.

That image took years to cultivate and it’s proved extraordinarily durable. Political consultants privately admit it’s one of the most effective pieces of authentic-looking personal branding in a generation. The word “authentic” does a lot of heavy lifting there.

What Downing Street demands

The problem is that No 10 has expectations. Not written rules, exactly. But expectations. State occasions, meetings with foreign heads of government, the weekly theatre of Prime Minister’s Questions — all of these carry enormous pressure to dress the part. A Prime Minister turning up to receive the French President in a zip-up fleece isn’t just a style choice. It becomes a diplomatic signal, whether intended or not.

A senior protocol adviser put it bluntly: “The office changes what’s acceptable. That’s not about vanity. It’s about how the country is represented in rooms where the stakes are extremely high.”

Burnham’s team will be aware of this. They’ll have gamed it out. The question isn’t whether he’ll wear a suit — he almost certainly will — but whether shedding the casual uniform means shedding something more valuable underneath it.

The Blair and Johnson problem

There’s precedent for this tension. Tony Blair spent considerable energy in his early years projecting approachability, before Downing Street slowly formalized him. Boris Johnson went the other direction, leaning into deliberate scruffiness as a performance of relatability. Neither quite managed to look natural once the full weight of the office landed on them. Both ended up looking like men wearing a costume — just different costumes.

Burnham is different in one key respect. His style isn’t performed dishevelment. It genuinely reflects how he moves through the world.

What comes next

Still, the transition will be watched closely. Image strategists suggest the smart move would be to retain signature elements — a particular colour palette, perhaps, or a specific cut — rather than making an abrupt shift that reads as capitulation to convention. Small anchors to the old identity can go a long way.

Whether Burnham can thread that needle remains genuinely open. The tracksuit got him to the top. Whether it travels with him is another question entirely.
