BUDAPEST, June 22 (Reuters) - Hungarian Prime Minister Peter Magyar said on Monday that his government would initiate the president's removal from office ‌with a constitutional amendment, and also launch a constitutional reform in ‌the autumn.

Magyar also told parliament that his government would launch broad economic, political and legal ​measures to rid Hungary of corruption, including the creation of a National Asset Protection and Recovery Office.

Following are key points from Magyar's planned anti-graft reforms, which he has dubbed "Operation Purgatory".

• The government will amend 47 laws to create the legal ‌foundations of a new ⁠National Asset Protection and Recovery Office investigating suspected misuse of public funds over the past two decades.

• Magyar says corruption ⁠has cost Hungarians 8% to 10% of gross domestic product in recent years.

• Lawmaker Gergely Gulyas of the previous ruling party, Fidesz, calls Magyar's speech "slanderous and appalling"

• ​Constitutional amendment ​to remove President Tamas Sulyok from ​office. Magyar has accused Sulyok, one ‌of Hungary's least popular politicians, of propping up right-wing former leader Viktor Orban's rule. Sulyok has said he had no political agenda and merely provided necessary checks and balances.

• Parliament to elect new president for a maximum of five years if and when Sulyok is removed.

• Comprehensive constitutional review, including ‌public consultations, to start in autumn. New constitution ​will be subject to a referendum.

• Legal ​changes to set age limit ​at 70 years for judges at the Constitutional Court, which ‌can block some legislation. Orban ally ​Peter Polt would have ​to retire as head judge.

• Reforms will enable two-thirds of judges to initiate removal of the heads of the Kuria or supreme court ​and the National Judicial ‌Office, subject to approval by two-thirds of lawmakers.

• Lawmakers' terms to ​be limited to 12 years.
