The results confirm the party's position as a dominant force after it won nearly 75 per cent of contested seats for Egypt's newly recreated Senate in August.

Parliament was already controlled by Sisi supporters but Nation's Future sharply increased its share of seats to 315 from 57 in the 596-seat chamber.

A small opposition block of leftist and independent deputies lost seats, official results showed.

Voters and politicians had expected Nation's Future to benefit from new electoral rules to lock in control of the parliament.

Lists headed by the party won all 284 seats allocated for pre-selected lists under a winner-takes-all system.

Nation's Future got 145 of these seats, according to election commission statements.

The party also won 170 of the 284 seats contested by individual candidates.

Another pro-Sisi party, the Republican People's party, won 50 seats and non-affiliated candidates won 93 seats.

Sisi can appoint 28 legislators directly.

Some voters and rival candidates accused Mostaqbal Watan of giving food or cash handouts to voters, accusations the party repeatedly dismissed.

Rival candidates and parties also filed complaints to the election commission alleging electoral fraud but all were rejected. Some have also taken complaints to the courts.

Turnout in the two main rounds of voting was 29 per cent.

Sisi has overseen a sweeping crackdown on political dissent since leading the ouster of former President Mohamed Mursi of the Muslim Brotherhood in 2013.

Sisi and his supporters say the measures were needed to stabilise the country.
