Been here for a week, heading towards Cadiz from Santander. The Spanish Government provide a 25 cent discount per litre on diesel. Repsol seems to offer an average of 1 Euro 89 cents at the pump, but then the discount is applied. Fill up again and the discount is 30 cents. On todays rate that is about £1.40 a litre in UK money. Sunak's 5p discount is little help.
