Environmental activist Wayne Kublalsingh rejected medical intervention over his hunger strike on Saturday and vowed to keep protesting against a controversial Trinidad motorway project.

Dr Kublalsingh has spent more than 100 days without food and said he would stop only if the government let independent mediators assess the project, which he says could hurt wetlands and remote villages.

He declined government offers of dialogue, saying community leaders had met officials repeatedly without results. “All we have got is malingering, procrastination and a high degree of insincerity,” said Mr Kublalsingh.

Works and Infrastructure Minister Surujrattan Rambachan said development company representatives were prepared to meet Dr Kublalsingh in January.

Mr Rambachan added the government was concerned about Dr Kublalsingh’s health.

“It’s up to those around him to urge him to end the fast and save his life,” he said.

The former university professor went on strike on September 17 and is down to 6st 4lb pounds from 9st 7lb pounds.
