There is not a local group though some rebels are active.
See https://animalrebellion.org/. This has details of their current campaigns, which some of us have been supporting locally – McDonalds (including McSit-ins) and Feed Our Future (campaign for plant-based days in schools and councils).
You might also be interested in The Plant Based Treaty, a new worldwide campaign, modelled on the Fossil Fuel Treaty and aiming to address the climate and ecological damage caused by food systems alongside that from fossil fuels. It is based round three principles of Relinquish, Redirect & Restore – each with specific details for what needs to be done. The treaty can be endorsed by individuals, groups, and all levels of government. For more details, and if you wish to endorse the treaty, see https://plantbasedtreaty.org/
