I dont think I have an inner monologue. I think in words only when imagining a conversation, or in this case, writing this comment. Otherwise I think in ...images maybe?
In most multiparty systems, a party needs to hold a certain number of seats in Parliament in order to be in power. If no party has enough seats after an election, they attempt to form coalitions in order to get enough seats and form a government.
A party leaving the coalition means that it'll no longer hold enough seats to have a majority. I dont know the specifics here, but they might be able to form a coalition with a different party, or require new elections.
