Everyone is invited to join the media launch, which takes place outside the Scottish Parliament, to show support for the forthcoming March + Rally in September.
TV and press will be present at the first of a series of awareness-raising events.
At the launch, more details on the September March + Rally will be published as well as information about further events planned in the run-up to the independence referendum in 2014.
Supporters of the campaign have sponsored an eye-catching large poster van, which will tour Scotland prior to the September March. The design of the van will be revealed at the media launch.
