President Asif Ali Zardari will tackle British Prime Minister David Cameron's uncalled for allegations of Pakistani support for terrorists, on a visit to Britain starting Tuesday, officials said. After wrapping up meetings with French leaders, Zardari heads to London and in talks with Cameron later this week will raise his claims that some elements in Pakistan back the Taliban, said a spokesman for the president. Cameron's uncalled for remarks and the fact that these were made in India had disappointed the people of Pakistan, said the spokesman in a statement Monday after Zardari met French President Nicolas Sarkozy in Paris. Zardari told Sarkozy it was unfortunate if some people continued to express doubts and misgivings about our will and determination to fight the militants to the finish, according to the statement. No other country in the international coalition has paid such a heavy price in this fight as has Pakistan, it quoted Zardari as saying.
