How do I use keys bound to a command with universal argument in Spacemacs?

Question

In spacemacs, a lot of commands have bound keys such as leader x a. For those commands that accept universal argument, how can I pass them to these command with key bindings? leader space leader x a does not seem to work.

I guess this question is the same as the one posed here: How do I hit the equivalent of `C-u` (of normal emacs) in Spacemacs?

Anyway: use SPC u (or leader u) and then the keystrokes for the command you want to use a prefix with.
