The price of petrol at the pumps has reached a new high, the AA has said.

The average price has risen from last week's record figure of 121.76p a litre to 122.14p.

Average prices have gone up 3.06p a litre between mid-November and mid-December 2010, the AA said.

Diesel, which is still some way off its all-time record high, has risen 3.12p a litre over the last four weeks and now costs an average 126.19p.

Compared with this time last year, the cost of filling a 50-litre petrol tank has increased from £54.26 to £61.07. A 50-litre tank of diesel has gone up in price from £54.93 to £63.10.

UK petrol car owners are now spending £8m a day more on fuel than a year ago.

Regionally, London and south-east England have the most-expensive petrol, at 122.7p a litre, while Scotland and Wales have the dearest diesel, at 126.7p a litre.

Petrol prices in northern Scotland are at or exceeding 130p a litre, with 129.9p in Ullapool and 133.9p in Stornoway. Diesel there now costs around 135p a litre, with 134.9p in Ullapool and 135.9p in Stornoway.

Petrol on England's motorways varies from 121.9p a litre to 129.9p and for diesel from 124.9p to 132.9p.

AA president Edmund King said: "This is a bleak mid-winter for millions of drivers. Milking motorists through higher fuel prices is over, as many are running dry and biting back, not because they want to but because they have no option."
