The group, renowned for its superhero-costume protests, is planning a media campaign around a series of billboard ads and motorway banners using McDonald's and Tony Blair as points of reference, and a number of stunts.
The ads, currently under review by F4J members and lawyers, include one describing the 'McDad' culture, whereby separated dads only see their children in McDonald's for a few hours a week. Another describes Blair as a 'crimeminister', claiming teenagers from fatherless families are more likely to commit crimes.
'We are trying to be provocative. That is what we do,' said F4J founder Matt O'Connor.
In response to the planned ad, a McDonald's spokeswoman told PRWeek: 'We are proud that our restaurants are recognised as popular destinations for parents and children. But we feel it would be wholly inappropriate for us to comment on something of such a political nature.'
