Pakistan's parliament will be dissolved at midnight on Thursday, a government minister said, giving details of the process leading to promised general elections.
The assembly is completing its full term under the shadow of the state of emergency declared by President Pervez Musharraf on November 3.
A caretaker government will be sworn in Friday to guide the country before elections Musharraf has promised by January 9.
"The national assembly will get automatically dissolved Thursday midnight (1900 GMT) on completion of its five-tear term," deputy information minister Tariq Azeem told AFP.
He said the name of the interim prime minister, replacing Shaukat Aziz, was also expected to be announced on Thursday.
"This is a historic moment for all of us," Azeem said, adding it would be the first time for 22 years that an assembly was completing its mandate.
Remaining provincial assemblies will dissolved on November 20.
