PM Persad-Bissessar made the announcement via a release.
She said having received a report from Mr Roberts she was now in the best position to make a decision on the matter.
PM Persad-Bissessar said she has the authority to make many decisions every hour as Prime Minister, but always does so with consideration of what is right and fair.
Experts from Mr Roberts’s letter were also sent with the release.
He categorically denied using illicit drugs tenure as Government Minister.
Mr Roberts said “it is with great sadness that I have watched a relentless media campaign designed to defame, hurt and disrespect not only me, but my wife, children and unborn child, as well as my constituents, my government and you, my beloved Prime Minister”.
He also denied using prostitutes which he said is being implied by the opposition.
