PORT-OF-SPAIN, Trinidad (AP) — Trinidad has lifted an entry ban for a U.S. political campaign strategist as the twin-island Caribbean nation prepares for general elections.

Trinidad's national security minister says Henry Bernard Campbell can enter the country and continue his work for the opposition. The American was previously denied entry based on the island's immigration laws.

Campbell is advising the United National Congress Party on its campaign strategy for the May 24 elections. Party leaders hade blasted the government for denying entry to Campbell.

The announcement of government's shift came Monday from National Security Minister Martin Joseph.
