Imran Khan used the word during a rambling budget speech in parliament, attacking his predecessors' foreign policies and saying that Pakistan's partnership with the United States in the war on terror was a mistake.

Khan also said the US government used abusive language against Pakistan, blaming the country for its failures in neighbouring Afghanistan and most of all - refused to tell officials in Islamabad of its operation against bin Laden in 2011 before carrying out the Navy SEALs night-time raid.

The special operations force swooped into Pakistan's military garrison town of Abbottabad in the middle of the night on May 2, 2011, killing bin Laden and several of his operatives.

"We sided with the US in the war on terror but they came here and killed him, martyred him and ... used abusive language against us (and) did not inform us (of the raid), despite the fact that we lost 70,000 people in war on terror," Khan told Parliament.

"The way we supported America in the war on terror, and the insults we had to face in return... They blamed us for every failure in Afghanistan. They openly held us responsible because they did not succeed in Afghanistan," Khan said.

Pakistan, Saudi Arabia and the United Arab Emirates were the only countries to recognise the Taliban government, which had harboured bin Laden as he planned terrorists attacks against the US.

After the 9/11 attacks, Pakistan turned and became an ally of the United States against the Taliban, who were ousted by a US-led coalition in November 2011.

However, opposition MP Khwaja Mohammed Asif criticised Khan for calling bin Laden a martyr, saying he had brought terrorism to Pakistan.

"He (bin Laden) ruined my country but he (Khan) is calling him a martyr," said Asif.

Since taking over, Khan claimed his government has reset the Pakistan-US relationship, elevating it to one of mutual respect, for which he also credited the personal rapport he has built with US President Donald Trump.

"No one insults us now," Khan said.
