I’ve added a new link to the Political Sites section on the Favorites page of our OSINT / i3 website at https://www.uk-osint.net/favorites.html#PoliticalSites

Consolidate (https://www.consolidate.org.uk/database) is a useful site which as well as showing an MP’s Register of Interests it also allows searching for who has given donations to individual Politicians and Political Parties in the UK
