In a statement here he said opposition parties have been 'isolated' as they left the people alone.
He said that it was the best time to rise above mundane politics and serve the people.
He advised the opposition parties to avoid politics on the most important challenge such as COVID-19.
The government, under the leadership of Prime Minister Imran Khan, has taken timely and far-sighted decisions to deal with the coronavirus situation, the CM said.
"How can those who mercilessly looted the national kitty talk about the welfare of masses?" He regretted that the opposition leaders tried to sabotage national unity despite the onslaught of coronavirus.
The negative role being played by the opposition during coronavirus has become a part of national history, he observed.
Usman Buzdar said the Pakistani nation will never forget the negative politics played by the opposition.
"Those who indulged in personal ambition in this hour of challenged have been fully exposed", the CM concluded.
