The average price of unleaded increased to 187.51p per litre on Thursday, up from 187.01ppl, the previous day.

Meanwhile, diesel jumped to 194.17ppl, up from 193.30ppl.

RAC fuel spokesperson, Simon Williams, said: “Petrol and diesel prices continued their stratospheric rises on Thursday, making the cost of filling a 55-litre family car £103.13 and £106.79 respectively.

“However, we’re hopeful that the scale of the recent increases is at last slowing and we’d expect the largest retailers who buy fuel most frequently to stop the pump price rot and even look at reducing their prices soon to reflect the fact they’ve been benefiting from lower wholesale costs over the last week.”
