(Adds PL's statement)
Simon Busuttil has stood by his stand against the indefinite suspension of Schengen arrangements by Malta, insisting the government was giving conflicting messages.
The Opposition leader said he had a problem with the government's decision because it did not tally with government's insistence that there was no terrorist threat.
"I agreed with the temporary suspension of Schengen because of the Valletta Summit and CHOGM but the wholesale removal of a right beyond these events raises questions about government's attempts to ensure peace of mind," he said when asked whether his position was in sync with popular sentiment that Schengen should be suspended in the wake of the Paris attacks.
On Sunday, Dr Busuttil tweeted his opposition to the Prime Minister's announcement that Schengen would remain suspended after CHOGM until more clarity on new rules is achieved in the EU.
Dr Muscat said the temporary suspension of Schengen had helped uncover a racket of foreigners coming to Malta with false passports.
But Dr Busuttil doubted this was the result of the Schengen suspension.
Dr Busuttil said the biggest threat to Malta was not coming from Schengen countries but from people coming from outside the EU with visas given to them by Malta.
He said it was scandalous that the government was handing out Schengen visas in their thousands from the consulate in Algeria, a number that ballooned over the past two years.
He was speaking at the end of a visit to Golden Harvest, where he was given a tour of the company's renewable energy drive.
OPPOSITION LEADER 'IRRESPONSIBLE'
In a statement this afternoon, the Labour Party said the Opposition leader was showing how irresponsible he was when he said that he had a problem with the indefinite suspension of Schengen because it did not tally with government's insistence that there was no terrorist threat.
The Opposition leader’s mask, the PL said, continued to be uncovered. He wanted to be against everything the government and the Prime Minister said and did even if he ended up contradicting himself in the process.
