Joe Garner said higher property prices and interest rates, together with steep increases in the cost of living, meant that housing affordability had become even more challenging.

He made his remarks as the UK's biggest mutual reported a near-doubling of annual profits on the back of buoyant mortgage demand.

Pre-tax profits jumped to £1.6bn in the year to 4 April - up from £823m in the same period a year earlier.

But Mr Garner, who steps down as chief executive next month, said of the outlook: "The emergence of higher inflation, which has been exacerbated by the war in Ukraine, is likely to exert a significant drag on the economy in the near term.

"Higher inflation will place significant pressure on household budgets, especially for those on lower incomes who also accumulated fewer savings during COVID-related lockdowns.

He predicted that housing market activity would slow from elevated levels that has seen average prices increasing at a double-digit annual rate as demand from those wanting to move home exceeds the number of available properties.

Mr Garner leaves the helm of the country's second-largest mortgage lender on 1 June - to be succeeded by former TSB boss Debbie Crosbie.

Nationwide said its financial performance was boosted by a strong economic recovery from pandemic lockdowns.
