Pakistani Prime Minister Imran Khan on Tuesday night addressed the nation and vowed to go after the "thieves who left the country badly in debt", Dawn reports.

The address followed a noisy budget session in the National Assembly and two major arrests — Leader of the Opposition in the Punjab Assembly Hamza Shehbaz by the National Accountability Bureau (NAB) and MQM founder Altaf Hussain by London police — earlier in the day. On Monday, former president Asif Ali Zardari was also arrested by NAB.

The premier announced that after putting to rest the initial focus of the government to stabilise the economy, his attention would be more targeted towards bringing the ones to task who had caused the country to fall into such dire straits.

"Pakistan is stable now. That pressure [to stabilise the economy] has been relieved. Now I will go after them [the corrupt politicians]," declared the prime minister.

"I'm making a high-powered enquiry commission with a one-point agenda: how did they raise the debt to Rs24,000bn in 10 years?"

"All those in power will be fully investigated by this commission which will prepare a report so that no one dare leave the country in tatters ever again."
