Musharraf, 69, will return to the country intent on leading his party in upcoming elections, a statement released by him said.
Musharraf plans to fly on a commercial airline into Karachi on March 24, then attend a rally attended by 50,000 people including more than 200 Pakistani expatriates from the US, Canada, the UK and the UAE, the statement was quoted by the CNN as saying.
He plans to lead his party, the All Pakistan Muslim League into Pakistan's general elections, which are slated for May.
Musharraf, who stepped down as President in 2008 after he was threatened with impeachment, has earlier brushed aside questions on whether he would be arrested on his return in connection with several cases against him, including the case related to the assassination of former premier Benazir Bhutto.
