Egypt’s Future of Homeland Party withdrew on Sunday from pro-Sisi parliamentary bloc Support Egypt, said a party spokesman without disclosing a reason for the withdrawal.
"We will announce the reasons for the withdrawal in the near future," Ahmed Samy told Ahram Online.
The Future of Homeland won 50 party-based seats, the second largest number won in the elections.
The Support Egypt bloc, headed by former intelligence officer Sameh Saif El-Yazel, has been seeking to recruit a sweeping number of parliamentarians to its ranks.
The bloc consists of over 400 parliamentarians from various political parties as well as independents, according to its members. A final tally of the bloc's list has not yet been announced.
The liberal Free Egyptian Party, which scored highest parliamentary seats with 65 seats, refused to join the Support Egypt bloc, saying that it had “unclear aims.”
The party, in a Saturday general meeting, added that it voted to expel one of its members that signed to join in the bloc.
Egypt's parliament is expected to be sworn in by the end of December, and will be composed of the highest number of MPs in the country’s 150-year parliamentary history.
The MPS are divided into 448 independents, 120 party-based deputies, and 28 presidential appointees.
