Purpler Winter, an annual social media campaign which goes viral every year, highlights and raises awareness around child abuse.

The campaign, which launches tomorrow on Twitter for just 24 hours, urges social media users to wear a purple item and share snapshots of themselves, while also talking about ways to spot, and stem, child abuse in its many forms.

People from around the world use this day to upload images and videos of support in a variety of languages. The campaign is supported by charities, celebrities, and survivors of childhood abuse.

If you are a Twitter user and you’d like to take part in the campaign, log in to the platform and type in #PurplerWinter, for all the latest updates and ideas on how you can get involved.
