Can Mike Ashley defy high street reality?

Separating heroes from villains in the great retail survival struggle is like spotting bent coppers in Line of Duty — whose sixth series, I’m pleased to report, has just finished filming. The plot just keeps twisting. Sir Philip Green, as I said last week, is seen as an irredeemable baddie; and most commentators (though not usually me) put sportswear tycoon Mike Ashley in a similar category, as an opportunist with a track record as a harsh employer. But now here he is, trying through his company Frasers Group to launch a last-ditch rescue for Debenhams, despite having lost £150 million last year in previous pursuit of the department store chain.

He can’t save all 124 shops and 12,000 jobs — but even saving half or a third of them would be remarkable. The point about Ashley is that he has no interest in cashing out, and a burning urge to prove his critics wrong.
