The National Assembly (“Pakistan lower house”) is the lower legislative house of the bicameral Majlis-e-Shura, which also comprises the Senate of Pakistan (upper house). The National Assembly and the Senate both convene at Parliament House in Islamabad. The National Assembly is a democratically elected body consisting of a total of 336 members, before 25th amendment they used to be 342 who are referred to as Members of the National Assembly (MNAs), of which 272 are directly elected members and 70 reserved seats for women and religious minorities. A political party must secure 137 seats to obtain and preserve a majority.
Members are elected through the first-past-the-post system under universal adult suffrage, representing electoral districts known as National Assembly constituencies. According to the constitution, the 70 seats reserved for women and religious minorities are allocated to the political parties according to their proportional representation.
Each National Assembly is formed for a five-year term, commencing from the date of the first sitting, after which it is automatically dissolved. Currently the National Assembly can not be dissolved by the President of Pakistan; it is dissolved by the Prime Minister of Pakistan.

According to The Constitution
The Speaker of the House is the presiding officer of the National Assembly. The speaker is assisted by the Deputy Speaker.

Apart from presiding over National Assembly debates, the Speaker may also assume the duties of Acting President, if the position is vacant (in case the President as well as Chairman Senate are not available).
The current Speaker and Deputy Speaker are Asad Qaiser (PTI) and Qasim Suri (PTI), respectively.
