Miriam Cates Facebook statement

For Miriam Cates, the choice after leaving Parliament was clear: step into the media arena and a policy institute, rather than pursue re-election or a different political seat. She is now shaping the conversation around family and child safety from outside Westminster—a position that gives her freedom to speak without whips, but also removes her from direct legislative power. For a former MP who changed the law on online safety, the next chapter will be measured by influence, not votes.
