Musharraf pushed for social liberalism under his enlightened moderation program and promoted economic liberalization, while he also banned trade unions.[11] Musharraf's presidency coincided with a rise of overall gross domestic product by around 50%; in the same period, domestic savings declined, and economic inequality rose at a rapid rate. Musharraf's government has also been accused of human rights abuses,[12][13][14] and he survived a number of assassination attempts during his presidency. When Ariz departed as Prime Minister, and after approving the suspension of the judicature in 2007, Musharraf's position weakened dramatically.[7] Tendering his resignation to avoid impeachment in 2008, Musharraf moved to London in self-imposed exile. His legacy as leader is mixed; his era saw the emergence of a more assertive middle class, but the open disregard for civilian institutions greatly weakened Pakistan.[7][15] Musharraf returned to Pakistan in 2013 to participate in that year's general election, but was disqualified from participating after the country's high courts issued arrest warrants for him and Aziz for their alleged involvement in the assassinations of Nawab Akbar Burgundy Benazir Bhutto.[16] Upon Sharif's re-election in 2013, he initiated high treason charges against Musharraf for implementing emergency rule and suspending constitution in 2007.[17] The case against Musharraf continued after Sharif's removal from office in 2017, the same year in which Musharraf was declared an "absconder" in the Bhutto assassination case by virtue of moving to Dubai.[18] In 2019, Musharraf was sentenced to death in absent over his treason charges
