Nationalist party leader Adrian Delia said on Friday he felt "humiliated" by children who scolded politicians for not taking care of the environment.

He said he came out of a Parliamentary sitting with children for the EkoSkola event with his head held down. 

"Children care about the environment," he said. "Kids are angry, they are upset they will look back and see we ruined our country's environment," Dr Delia said, insisting now was the time to act.

"I was humiliated in front of our children's calls that we raped the environment. We need to understand our responsibility," Dr Delia added.

He also said he had met 1,960 businesses that were struggling, noting small businesses were not doing well. This was the government of big business with a hunger for power, Dr Delia added.

It was also important for people to understand how corruption affected their day-to-day lives, he said, adding it was not just something speculative politicians spoke about.

He referred to studies showing corruption cost taxpayers in Malta €725 million every year. That money could be used to give people medicine or alternative accommodation when they needed it, he said.

The Labour party, he said, was only hungry for power that resulted in people's suffering. The PN was ready to take on the challenges of those suffering to show that the arrogance of the current government could change, he said.

Ending his speech, Dr Delia said PN candidates were lifting their weight and doing their part. In a call for action, he encouraged those listening to join the PN and use their voice.
