HAVANA (Reuters) – Cuba’s national assembly named former President Raul Castro to head the commission charged with carrying out changes to the constitution that would provide legal backing to the island’s economic and social opening. The nomination of Castro, 86, adds to signs the presidential handover in April to Miguel Diaz-Canel, 58, does not herald sweeping changes to the island’s one-party socialist system. Castro is to remain head of the Cuban Communist Party until 2021.
