LONDON, June 24 (UPI) -- British Prime Minister David Cameron will step down by October after Britain voted Thursday to leave the European Union after 43 years.
Cameron, who has served as premier for six years, announced his resignation in front of the prime minister's residence at 10 Downing St. on Friday morning after the so-called "Brexit" was approved by the British public.
Cameron warned of economic and national security calamity if the Britain left the 28-nation bloc and strongly urged his countrymen to vote to remain in the EU. A slight majority, 52 percent to 48 percent, voted to leave.
"The will of the British people is an instruction that must be delivered," Cameron said. "I do not think it would be right for me to be the captain who steers the country to its next destination."
He will step down during Conservative Party's annual conference in October.
