LONDON (Reuters) - Prime Minister Rishi Sunak will face more pressure from his fractious party to cut taxes after a blistering critique from Boris Johnson, even if the British leader can most probably stave off more resignations.

Former prime minister Johnson quit as a lawmaker late on Friday over an investigation into rule-breaking parties during the COVID pandemic, with a statement that deepened the divisions in the governing Conservatives and further hindered its efforts to make a comeback in the polls before an election due in 2024.
