The Labour Party has blamed the shadow minister for the environment, Jason Azzopardi, for having transferred land at Bulebel to Malta Industrial Parks.
It said the land was transferred in December 2009 for the building of factories, when Dr Azzopardi was responsible for lands.
The Nationalist Party last week urged the government not to use agricultural land to extend Bulebel Industrial Estate.
It said Dr Azzopardi could not be credible in condemning MIP for considering the use of the land, when he had himself transferred it for factory-building.
This case also reflected badly on Opposition leader Adrian Delia, who had chosen as environment shadow minister a person linked to scandals in the use of public property, the PL said.
