New Delhi: Britain has admitted that it has not been "effective enough" to make Pakistan comply with its promise of ending cross-border terrorism in Jammu and Kashmir and feels that Islamabad needs to do more on this count.

British High Commissioner to India Sir Rob Young says that London would keep up pressure to see an end to cross-border terrorism, infiltration into Jammu and Kashmir, flow of supplies and removal of infrastructure but advocates that India and Pakistan hold dialogue to "sort out differences".

"We have not been weak. In fact, we have been strong and effective in the last 18 months. But we have not been effective enough," Young said participating in Karan Thapar's 'Court Martial' programme telecast on SAB TV on March 6 night.

"More needs to be done by us and Pakistan President Pervez Musharraf," he said.

Young was responding to a question on a recent statement by Prime Minister Atal Behari Vajpayee in Parliament that United States and United Kingdom had been "weak" in making Pakistan fulfil its promise on ending terrorism.

"We have a serious undertaking from President Musharraf on the question of cross- border terrorism. My government's position remains the same - that cross-border terrorism has to be stopped permanently and sincerely," he said, adding Britain would continue to "persuade" Pakistan.

He said Britain was "closely focussing" on this issue and was "still very concerned" on the matter.
