To be fair to John Lewis, the partnership told us that half-year profits would be close to zero back in June.

Even so this morning’s results are difficult to shrug-off.

John Lewis says it’s been squeezed between rising costs, due to the weakness of sterling, and falling prices due to ferocious competition.

The partnership’s “never knowingly undersold” promise means it has price-matched its rivals all the way to break even.

The truth is the partnership is not in anything like the sticky situation that perhaps the headline numbers suggest.

Profits have been wiped out largely because the group has prioritised investment (£400-£500m a year) in the business.

Debt has been reduced, cash hoarded.

The group has spent money improving cyber security and data protection and has cut its pension deficit.

The department stores should have been making hay while its rivals - House of Fraser and Debenhams - struggled. Instead they lost money.

Sales at John Lewis fell 1.2%.

In the circumstances that should be cause for concern.

The partnership seems determined to hold onto its 50 department stores.

Unless it arrests the decline in sale, the case for doing so will get weaker.

John Lewis says the outcome of Brexit negotiations makes the future hard to call.

The Chairman of John Lewis, Charlie Mayfield, has warned about the impact of “no deal” previously and did so again today.
