triggered by a cdu politician's decision to cooperate with the far-right party and the pro-business fdp. this was against the wishes of the cdu national leadership and was seen as political taboo in germany. >> what we learned from what happened is the powers within the cdu want to move the party to the political rate. the backlash has been so massive a party is now taking this very seriously. >> if the cdu does move further to the right, that could threaten angela merkel's coalition government. members of parliament are appealing for calm. >> a leadership battle in the party is surely something thatt is not helpful right now, but we members of parliamament will continue to provide stability. >> this governing coalition is able and willing to work. it has been a tough couple of months for the social democrats, but i do not one-time make the job anymore difficult for the cdu at the moment. >> now, will most likely be up to chancellor merkel to resolve the crisis. her government cannot afford such turmoil when it takes over the presidency of the european union. brent: the world health org
