Injunctions

Questions:

How do I get an injunction against my ex partner and how much does it cost?
Someone has put a video/photograph of me on the internet/is showing video footage of me in a compromising position to friends etc., without my permission, what can I do?
Will the police get an injunction for me?

I've heard that the MoT is changing – how will that affect me?

For police non-emergencies dial 101
