Mr Sharif has backed the lawyers' demand for the judges to be reinstated and has called on Pakistanis to join the demonstration.
"The march is going to be peaceful, it is a march which has been called by the lawyers' community of the country and we are supporting this cause because we think that this march can certainly promote democracy in this country," Mr Sharif told the BBC.
The current president was freely elected but that does not mean that Pakistan was a democracy, Mr Sharif said.
"You can't have democracy without an independent judiciary, without judges who are loyal to the state and we don't want judges who are loyal to one single individual.
"Therefore, I think we need to have all those amendments in the constitution repealed which were introduced by dictator [former President Pervez] Musharraf and we want the rule of law back in to this country. And we don't think without these things we will have democracy back in Pakistan."
The sackings in November 2007 of some 60 senior judges, including the then-chief justice Iftikhar Chaudhry, sparked countrywide protests and ultimately led to Mr Musharraf's resignation.
