Understanding the paths through the corridors of power can be vital to your campaign's success.
Bibi Van Der Zee’s book Rebel Rebel examines lobbying parliament and provides a range of tips.
BritCits was formed in 2012 in direct response to the attack on British citizens and residents with non-European family members.
As part of their campaign, BritCits prepared a pack of case studies of those affected - currently standing at around 200 families. Many of these stories can be read on their website and forum.
They lobby MPs and MEPs, and their packs contributed towards evidence at the recent All Party Parliamentary Group inquiry on family migration. They work closely with other campaign and community groups and attend meetings on this and related migration issues.
They have built a self-supporting community where those affected can support each other, and share information on the various options available, such as legal options, free movement rights and local media.
Their aim is to change the rules, whilst working with each family, one at a time, as they continue to work to raise awareness of these situations.
