Egypt's government has denied state media reports that it has decided to dissolve the Muslim Brotherhood.
A social solidarity ministry spokesman was quoted as saying it would revoke the Islamist group's non-governmental organisation status "within days".
But a prime ministerial aide, Sherif Shawki, told the BBC the solidarity minister had not issued any decision.
The military authorities have launched a crackdown on the group since ousting President Mohammed Morsi on 3 July.
Dozens of senior Brotherhood figures, including its general guide Mohammed Badie, have been detained over allegations of inciting violence and murder.
