The Nationalist Party has called on Labour leader Joseph Muscat to investigate former ministers after shadow minister Chris Cardona last month acknowledged on a radio programme that there was corruption under the 1971-1987 Labour governments.
Dr Cardona had said there was no doubt that corruption had taken place, the PN said.
The party said that since a number of ministers of the time were still involved in politics, it was calling on Dr Muscat to investigate what had happened, since ministers were collectively responsible.
The party was reacting to comments on corruption made this morning by Dr Muscat.
It said the government had strengthened the institutions of the country as part of the fight against corruption, in contrast to the Opposition, which had even walked out of the Committee for Democratic Change, where further strengthening of these institutions was on the agenda.
