Pakistani President Asif Ali Zardari's five-day visit to Britain has been overshadowed by a controversy over British Prime Minister David Cameron's comment last week that Pakistan should not "look both ways" when dealing with militant groups.
Made during a visit to Pakistan's arch-rival India, the remark angered Pakistanis and strained ties with Britain.
Both leaders put a positive gloss on their relations after talks at Cameron's official country residence at Chequers, northwest of London.
"Storms will come and storms will go and Pakistan and Britain will stand together and face all the difficulties with dignity," Zardari said.
Cameron spoke of an "unbreakable relationship between Britain and Pakistan based on our mutual interests".
The leaders took no questions from reporters after making short statements. Zardari has faced criticism at home for travelling to Europe when devastating floods in Pakistan have killed more than 1,600 people.
"We engaged in a conversation like two adults do ... and we talked about the positives," Zardari told the BBC when asked if the two leaders had discussed Cameron's remarks in India.
PLAYS DOWN LEAKS
Cameron spoke days after U.S. military reports published on the WikiLeaks website detailed concerns the Pakistan's Inter-Services Intelligence (ISI) agency had aided Taliban militants in Afghanistan, where Britain has 9,500 troops.
Zardari denied it was official ISI policy to support the Taliban. "I wouldn't go that far. (The leaks) have been rubbished by everybody ... Most of it is hearsay," he said.
Pakistan had lost "more soldiers than the world put together" in the fight against militants, said Zardari, the widower of murdered former prime minister Benazir Bhutto.
"I've lost my wife ... my personal friends ... so I don't think anybody doubts our intentions on this war, but there can always be weaknesses which need to be strengthened ... Pakistan needs more resources," he said.
After his talks with Zardari, Cameron discussed Afghanistan and Pakistan in a phone call with U.S. President Barack Obama.
Farzana Shaikh, a Pakistan expert at London's Chatham House think tank, said the key question was whether Zardari could persuade people back home that he had put across Pakistan's point of view in his talks with Cameron.
"I don't think he's really got very much to show for it ... In that sense Mr Zardari stands even more weakened," she said.
Pakistan's spy chief cancelled a trip to London in protest against Cameron's comment, raising concern Britain could be cut out of important intelligence about domestic terror plots.
British and Pakistani government officials denied there had been any damage to intelligence cooperation.
Cameron and Zardari issued a communique pledging to intensify counter-terrorism cooperation and strengthen trade ties, and Cameron accepted an invitation to visit Pakistan.
