A national demonstration titled 'Ġustizzja' (Justice) is being organised by the Civil Society Network on Sunday.
The network invited the public, non-governmental and civil society organisations and political parties to take part.
The demonstration will start at 4pm from City Gate in Valletta.
The network invited participants to carry Maltese flags.
The demonstration follows the murder last Monday of journalist Daphne Caruana Galizia.
