A Zimbabwean court on Friday stopped the planned weekend wedding of Prime Minister Morgan Tsvangirai after his ex-lover claimed they were still married, a lawyer said. \"The marriage licence that had been issued to the premier has been cancelled. There is in existence a customary law marriage between the prime minister and Ms Locardia Karimatsenga (Tembo),\" Everson Samkange said. \"If he goes ahead with the wedding he will be committing bigamy.\"
