Protests, cheers on the streets of London as Brexit is finalized

Brexit supporters celebrated the U.K.’s historic departure from the EU after it was formalized on Friday after nearly four tense years of back-and-forth. The country’s first order of business will include negotiations over trade and security as it will no longer abide by the trading bloc’s rules. Roxana Saberi is in London where protesters and supporters are letting their emotions out on full display.
