Prince Charles and Pakistan's president have discussed the case of a Briton sentenced to death in the country.
The royal couple have begun a five-day tour of Pakistan
In a 45-minute meeting with General Pervez Musharraf, the pair spoke about Mirza Tahir Hussain, terrorism and last year's earthquake.
Hussain, originally from Leeds, was convicted of murder under Islamic law.
Prince Charles, who is in Pakistan for five days with the Duchess of Cornwall, also launched a scheme aimed at helping poor youngsters become entrepreneurs.
Hussain, who was originally acquitted of murdering a taxi driver 18 years ago, had been due to be hanged during the royal trip.
However, the sentence has been delayed until after 31 December after both the prince and Prime Minister Tony Blair expressed their concerns.
A senior Pakistani diplomat told the Press Association news agency: "Charles stopped and asked the president about the issue and Musharraf told him that we are already looking into this case and our effort will be to handle it in a way that satisfies both sides."
Details have not been officially released about what the prince said regarding the matter during his meeting with the president.
BBC Royal Correspondent Peter Hunt said that there is "a fear that applying too much overt outside pressure could backfire".
"The focus is on private negotiations, not public pronouncements," he said.
Mr Hussain's brother Amjad said he was "grateful" that Prince Charles had "made representations" on behalf of his brother.
At his meeting with Gen Musharraf, the prince also spoke of Britain's gratitude for Pakistan's help in the fight against terrorism, and in particular in the wake of the bomb attacks on London.
A Clarence House spokesman said: "The prince thanked the president for his help with 7/7 and tracking down those responsible."
The prince also launched a youth forum at the prime minister's residence.
It aims to provide loans and mentoring to young Pakistani entrepreneurs with funds from the Prince's Trust.
Charles has met with the Pakistani Prime Minister Shaukat Aziz.
He said: "You have to build the mentoring capacity because it is easy to give money, but actually the crux of the matter is the advice."
Meanwhile, the Duchess of Cornwall separately met the president's wife, Begum Sehba Musharraf, and the wives of other officials.
During their tour of the country, the royal couple will also travel to the areas of the country left stricken by last year's earthquake, which killed more than 75,000 people and left many more homeless.
They are also due to visit a madrassa, one of the Islamic schools of which there are about 20,000 in Pakistan.
The royal couple will be surrounded by intense security for the duration of their stay.
The official foreign visit is taking place despite a Foreign Office warning of a high risk of terrorism in the region.
