Nahda Party, an Egyptian Islamist party pending recognition, has said it will merge with Fadila Party, an Islamist party established by senior Salafi figures.
Nahda's chariman, Mamdouh Ismail, said Fadila Party members proposed the move.
On his Facebook page Monday, Ismail said the merger conforms to his party's objectives, which seek a strong and united Islamist political entity.
Ismail did not say whether the combined parties will adopt a new name or carry Fadila Party's name, since Fadila Party was established before Nahda.
He hailed the merger as a "new dawn for serious Islamic action that will help the nation overcome its current setback."
Observers believe Islamist groups, which have been increasingly active since the resignation of former President Hosni Mubarak, are the most prepared for the upcoming legislative elections.
Freedom and Justice Party, the political arm of the Muslim Brotherhood, had announced it would run for 50 percent of parliament seats during the elections, scheduled for November.
