Alok Sharma, who is also president of this year's climate summit, has told Prime Minister Boris Johnson that he would rather give up his position as business minister than step down from his role in climate change envoy, the newspaper reported.

In December, Johnson's office denied a report that he wanted his predecessor David Cameron to take over from Sharma as president of next year's UN COP26 climate change summit.
