David Davis, the United Kingdom's Brexit Secretary, resigned from Prime Minister Theresa May's Cabinet late Sunday night after weeks of speculation, intensifying the chaotic struggle to define what Brexit will look like and putting May's position at risk.
The big picture: Davis, an advocate for a "hard," lasting Brexit, made his move one day after May's Cabinet agreed to a "collective" plan for the U.K.'s ongoing negotiations with the European Union. Per the BBC, that plan was viewed by many as a "soft" version of Brexit, choosing to maintain a close economic relationship with the EU that created a "common rule book" between the two entities.
