Pakistan summoned Britain's envoy in Islamabad on Monday over comments by British Prime Minister David Cameron suggesting it was not doing enough to fight terrorism, officials said.

Adam Thomson, the British High Commissioner to Pakistan, was summoned to the foreign ministry to clarify remarks Cameron made during a visit to India last week, a Pakistani official said.

The comments caused anger in Pakistan and the country's spy chief cancelled a trip to Britain in protest, though President Asif Ali Zardari still plans to visit Britain later this week.

A British Foreign Office spokesman confirmed that Thomson was meeting Foreign Minister Shah Mehmood Qureshi at the request of Pakistan's foreign ministry but gave no further details.

Cameron, speaking last Wednesday in India, Pakistan's arch rival, told Islamabad it must not become a base for militants and "promote the export of terror" across the globe.

Images of protesters in Karachi burning an effigy of Cameron in protest at his comments have received widespread television coverage in Britain.

Pakistan's envoy to Britain, Wajid Shamsul Hasan, said he had personally dissuaded Britons of Pakistani descent from demonstrating against Cameron's remarks before Zardari's visit.

The Pakistani leader is due to travel to London from Paris, where he arrived on Sunday for talks with President Nicolas Sarkozy on security and economic issues as part of a three-day visit.

Zardari is expected to meet Cameron on Friday at the British prime minister's official country residence, Chequers, before addressing a rally of political supporters among Britain's million-strong Pakistani community on Saturday.

Pakistan's help is crucial for U.S. and Western efforts to stabilise neighbouring Afghanistan, where Britain has 9,500 troops battling the Taliban.

Pakistan has launched a large military offensive against al Qaeda and Taliban militants in its northwestern provinces bordering Afghanistan, but recent criticism of its alleged ties to the insurgents have put the government on edge.

Cameron's remarks came days after classified U.S. military reports published on the WikiLeaks website detailed concerns that Pakistan's Inter-Service Intelligence agency had aided the Taliban while Pakistan's government was taking billions of dollars in U.S. aid.
