National Security Minister Jack Warner has said that former vice-chairman of the Congress of the People (COP), Vernon de Lima, fears his legal practice will suffer as he (Warner) clamps down on crime.

Warner knocked De Lima during his contribution to the debate to repeal section 34 of the Administration of Justice (Indictable Proceedings) Act at Wednesday's emergency Parliament sitting.

De Lima had filed a motion with an ultimatum—that the Prime Minister fire Warner or the COP would cut ties with the People's Partnership government.

The motion was defeated and the ultimatum of the COP leaving was removed.

The call for Warner to be removed was however maintained.

De Lima resigned his post following the defeat of the motion but remains a member of the COP.

Warner noted that Opposition Leader Dr Keith Rowley had said that he (Rowley) had nothing to fear in terms of police investigations.

"Madame deputy Speaker, I want to say to him as well and to this country, me too, I have not been investigated as much as he has been but even for the future, I never will be ......and that includes the comical behaviour of a so called vice chairman of the COP, a man who almost exclusively represented drug traffickers, exclusively, Dole Chadee also called Nankissoon," said Warner.

"A man who exclusively represented a man charged for four murders and who got away on three occasions and on the last time he failed. On the last time when he failed...... that murderer whom he represented on four occasions...when he failed the last time, he had with him Peter Thornton and Ronald Thwaites as his assistant and also a junior member of this Parliament as well," Warner added.

He went on to name other persons who had criminal cases whom De Lima had represented.

"The only thing that makes him more comical is Leary Joseph and what is even more painful is that he has some political colleagues in his corner because at the time he was a big lawyer he used to eat ah food," said Warner.

"After the demise of the Chadee family, that so called big shot lawyer had nothing to do until 2010, his work had dried up, when Rick Gomes was charged with trafficking $13 million tonnes of coke, fled the country as a fugitive and was tried by Gillian Lucky...so the fear therefore is that if the Minister of National Security were to succeed at all that lawyer and others like him will be out of business," said Warner.
