Chancellor Rachel Reeves has faced growing pressure to scrap planned fuel duty rises after fresh turmoil in the Middle East sent oil prices sharply higher. With the Spring Statement due later today, critics have warned that now is not the time to increase taxes on drivers and increase petrol and diesel costs.
