By Elizabeth Piper and Kylie MacLellan LONDON (Reuters) - Britain could have a new prime minister by early September, the ruling Conservative Party said on Monday, after David Cameron started laying the groundwork for his successor to trigger the country's exit from the European Union. The government is under pressure to fill a vacuum left when Cameron announced he would resign by October after Britain ignored his advice and voted to leave the 28-member bloc in last week's referendum. Triggering a leadership battle that could draw in some of his closest advisers, Cameron urged MPs to work together in the meantime.
By Sarah Marsh HAVANA (Reuters) - A large "Four Points by Sheraton" sign has gone up outside the Havana hotel that this week becomes the first in Cuba to operate under a U.S. brand since the 1959 revolution. The military-owned Gaviota 5th Avenue Hotel, close to the Caribbean seafront, is one of two hotels that Starwood Hotels & Resorts Worldwide agreed to manage in a multimillion-dollar deal with Cuba in March. For decades, such arrangements have been prohibited under the U.S. economic embargo of the Communist-ruled island.
