A British-ism has been distorted by popular usage ~ Begs the Question. Begs the question means an assumption is made without proof. It is not synonymous with “poses the question” or “asks the question.” It is an expression in itself and shouldn’t be followed by … a question!
Writers should avoid the usage because it’s antiquated. “Beg” in old English meant the same as “to take for granted.” If what you intend to write is “poses the question” or “raises the question,” say so. Don’t “beg” the question.
