Photos: Before the resignation, the colorful reign of Britain’s Boris Johnson

LONDON — Prime Minister Boris Johnson announced his resignation Thursday amid a mass revolt by top members of his government, marking an end to three tumultuous years in power in which he brazenly bent and sometimes broke the rules of British politics.
