Paralegal roles – just LLB or also LPC?

Do I need the LPC to get a paralegal role?

I have just finished my LLB, but I haven’t managed to get a training contract. I plan to spend the next year looking for paralegal positions whilst continuing to apply for TCs. I can’t really afford to self fund the LPC and hopefully paralegal work will make my applications stronger. However, while many people say firms prefer LLB graduates, many of the paralegal ads I have seen ask for the LPC? What do you think?
