There should be a "high bar" to get rid of a sitting prime minister, a senior Tory said after Boris Johnson refused to say if he would quit if found to have broken coronavirus laws.
Business minister Paul Scully said he would need to "see the context" of any findings against Mr Johnson before making a decision on the Tory leader's future.
His comments follow reports that at least two Cabinet ministers will withdraw support from the Prime Minister if he is issued with a fixed penalty notice for flouting the restrictions imposed by his Government.
