What was the source of the political pressure?

Dear Editor,
Is it true that when President Jagdeo was advised by a top diplomat that assistance for the police depended on finding a commissioner of police other than Henry Greene that he said he was under intense political pressure to stick with Mr Greene?  If so, what was the source of the political pressure? The public needs to know what pressure can be applied to their Head of State.
Yours faithfully,
Hamilton Green
