Pakistan's President Asif Ali Zardari has returned to Pakistan after receiving medical treatment in Dubai, officials say.

He landed at an airbase in the southern city of Karachi.

His departure to Dubai on 6 December for treatment of a heart condition led to rumours, denied by officials, that he might resign.

It is not clear when he will resume his duties as president. His office earlier said he had been advised to rest.

A statement last week said that all tests carried out on him had produced results "within normal range".

Pakistan's civilian government has been under pressure in recent weeks over a scandal involving a leaked memo in which officials allegedly sought US help against a possible military coup earlier this year.

President Zardari, 56, denies any role in the memo.

Pakistan's relations with the US have taken a turn for the worse since the American raid in May which killed al-Qaeda leader Osama Bin Laden.

Since then, several senior US officials have accused Pakistan of backing militant groups that carry out attacks against Western and Afghan troops across the border in Afghanistan.

Pakistan has vehemently denied the allegations.
