London, Nov 5 (IANS): Days after Islamabad summoned the British High Commissioner to lodge a protest over the display of anti-Pakistan slogans on London cabs, transport authorities in the British capital have ordered the immediate removal of offensive advertisements.

According to Radio Pakistan, the transport company confirmed initiating an inquiry into the matter while assuring disciplinary action against perpetrators of the malicious campaign.

The development came after Pakistani social media users spotted the cabs in London.

On Friday, the Foreign Office issued a statement saying: "Foreign Secretary Tehmina Janjua called in British High Commissioner Thomas Drew to convey Pakistan's serious concern over the controversial slogans."

It added: "The High Commissioner is informed that Pakistan, in line with the UN Charter, rejects actions and advertisements with malicious content that impinge on our sovereignty and territorial integrity."

In September, Islamabad had summoned the Swiss ambassador over the public display of anti-Pakistan posters by a group in Switzerland.
