ISLAMABAD: The revelation of spying on a major political party of Pakistan is a grave, unwarranted and totally unacceptable interference in the internal affairs of a sovereign country and is condemned, said the Pakistan People’s Party (PPP) spokesman Senator Farhatullah Babar in a statement issued on Wednesday.

The PPP expressed grave disappointment over the revelation that the United States’ National Security Agency (NSA) had been spying on the party in 2010.

The PPP called upon the government to take up the issue at the diplomatic level and seek guarantees that such grave violations of international law will not take place in the future.

“Such insensitive operations and unacceptable interference in the affairs of a political party of a sovereign country will serve no purpose except to increase resentment and distrust,” the PPP spokesman said.

Senator Babar said that those who have violated the norms of responsible behavior by spying on the political institutions of a sovereign country owe an apology.

According to media reports, declassified documents have revealed that the NSA had been spying on the PPP government in 2010.
