The big mistake political campaigners often make when they come up with slogans for their candidates is hubris.

They assume that the pithy little phrase they have dreamt up to encapsulate their candidate’s credo is an original. A gem they have found in the rough which they will polish until it shines.

To her detractors, she’s the ‘continuity Corbyn’ candidate, but it seems Rebecca Long-Bailey might be drawing inspiration from more mainstream Labour figures.

On Saturday, during the leadership hustings in Liverpool, she referred to her beliefs as “aspirational socialism.”

It’s a neat little line, combining, as it does, the ‘S’ word, which pleases the grassroots, with something vague and modern sounding. Who could be against people having aspirations? Rather than levelling down – the traditional criticism of left-wing politicians – it implies levelling-up. ‘You can still do well, but we just want more people to do well.’

Well, for someone deeply committed to Labour’s Green Industrial Revolution, Long-Bailey clearly practices what she preaches when it comes to recycling.

‘Aspirational socialism’ was used by Andy Burnham in his 2010 leadership campaign. The one where he came fourth in a field of five.

Perhaps, though, there’s an older vintage?

Here’s Long-Bailey’s predecessor as MP for Salford, Hazel Blears, back in 2010: “New Labour is about aspiration and ambition, which is absolutely how I come to be doing what I do, because my parents were ambitious and aspirational for me.”

Continuity Corbyn or Version 3.0 New Labour?
