A protest in solidarity with Popular Current member Ahmed Douma will take place in front of New Cairo Court on Monday.
The protest will coincide with an expected verdict against Douma, who has been detained since 30 April, for insulting President Morsi and calling him a criminal.
The 'We Will Free Them' campaign against the arbitrary detention of political activists organised the protest.
In January, a report by the Arab Network for Human Rights Information (ANHRI) stated that the number of lawsuits filed for insulting President Morsi exceeded those filed for similar accusations under all Egyptian rulers since 1892.
Douma, who had been an activist since the Mubarak years, had been previously arrested during the SCAF rule, in 2012, following a clash with military personnel in front of the Egyptian cabinet headquarters near Cairo's Tahrir Square.
Accused of incitement and vandalism, he was conditionally released last April pending further investigation.
On 16 March, Douma was beaten along with other activists by Brotherhood supporters while painting anti-Brotherhood graffiti outside the group's headquarters in Moqattam.
The leftist activist opted not to file a legal complaint against the Brotherhood due to his lack of trust in the justice system vowing to fight the group politically, instead.
