British Prime Minister Boris Johnson pledged to leave the European Union by the end of October.

In a speech to the government after he was officially appointed by Queen Elizabeth II, Johnson promised to have a better new agreement with the Union and that the exit from the BRICT would be without excuses or exceptions, he said.

Johnson insisted that the outcome of the referendum should be respected, noting that he had full confidence in ending the exit within 99 days.

Johnson said he was waiting for work on the BRICEST file, which faced many obstacles during the last period of his predecessor, Teresa Mai.

Earlier in the day, former Prime Minister Teresa Mae formally submitted her resignation to Queen Elizabeth at Buckingham Palace.
