Liam Fox, the defence secretary, was tonight forced to abandon a private visit to Sri Lanka this weekend after a row with William Hague, who feared that he would upset Britain's carefully balanced approach to Colombo.
Fox announced his change of heart as US embassy cables leaked tonight provided fresh allegations of the Sri Lankan government's complicity with paramilitary groups in last year's offensive against the Tamil Tigers.
Labour accused the government of adopting a "chaotic" approach to diplomacy when Fox announced that he would instead make an official visit to the country in the new year.
Fox's decision came after talks with Hague, the foreign secretary, and a warning by the British Tamils Forum that his trip would send mixed messages to President Mahinda Rajapaksa, who is facing strong international pressure for an investigation into allegations that Sri Lanka forces committed war crimes.
