Dual wield parrying - 2 chances?

By player1499614, in WFRP Rules Questions

I'm sure this has been answered before, but I could not find it. When a character is using 2 weapons, then uses the "parry" skill, does he / she have an opportunity to parry with both mainhand and offhand weapons, or just mainhand?

Thanks for your help!

One Action Card => one Action.

Same problem would occur with shields.
