Opposition leader Dr Keith Rowley has projected that the People's Partnership Government will spend nearly half a trillion dollars by the time this administration leaves office in 2015.

He said last Friday the country has seen very little evidence of that expenditure.

In front a crowd of a few hundred people at Piggott Corner in Belmont during the People's National Movement's (PNM) post-budget rally Rowley said:

"These same jokers who had a problem with PNM spending less than they are spending now when the PNM had more money. They are passing bigger budgets when we have less money," he said, adding that when in opposition they accused the PNM of being profligate with the public purse.

Rowley said while people can see evidence of the PNM's spending with the high rise buildings that now house government departments and divisions, there is very little the Partnership can show for its huge income and expenditure budget sheets.

The Government's 2012 budget was $58 billion with a $7 billion deficit, the largest in the country's history following up on a budget of $54 billion the previous year.

Turning his attention to the Housing Development Corporation, the PNM political leader said there was bid-rigging in the Government purchase of a parcel of land in Calcutta, Couva. Rowley said bidders never existed and that it is not coincidental that the Minister of Housing Dr Roodal Moonilal addressed that situation during last Friday's sitting of Parliament.

Rowley said the property was valued at $65 million by surveyor Lindsay Scott but was then re-evaluated at a $200 million cost.

"Who is the person that offered $200 million...any kindergarten child could see.. you get the valuation down below with the evaluator. Then you get a fake buyer on top to bid with a high price. Then the cabinet pitches their approval at the high price. Then they sell the lands for $175 million. We are not stupid!" he said.

Rowley added that the Integrity Commission had a responsibility to ensure that public money is spent fairly and that citizens get value for their money.
