The Met Office warned ministers to expect an ‘exceptionally cold winter’ but then kept the prediction secret from the public.
The forecaster decided not to reveal the information because it was embarrassed after wrongly predicting a ‘barbecue summer’ in 2009, BBC analyst Roger Harrabin said.
Instead of a seasonal forecast, it offered only monthly snapshots.
As temperatures fell to a record low, train services were badly disrupted, roads were covered by snow and thousands were stranded at Heathrow as flights were cancelled and the airport struggled to clear the backlog.
