Leading a 40-member delegation, Sharif visited Bhutto's grave at Garhi Khuda Bakhsh in the southern Sindh province, said the report.

Bhutto was killed in a suicide attack on Thursday after addressing an election rally in the garrison city of Rawalpindi. The suicide bomber launched the attack when Bhutto was leaving the venue of the public meeting.

PML-N spokesman Siddiqul Farooq said that Sharif's delegation was aimed at showing unity with the people of Sindh.

Sharif has already announced boycott of the Jan. 8 general elections as protest against the assassination of Bhutto.

Bhutto's son Bilawal is expected to announce the "will" of his mother about the future of Pakistan People's Party (PPP) including the new leader on Sunday when the leaders of the PPP will meet to decide whether or not to take part in the general elections.
