Cleared my Plab 2

Hi! I cleared my Plab 2 recently, but unfortunately my ielts score expired just a few days after I appeared for the exam. Now my question is that I order to get full GMC registration do I need to give ielts again and get a similar score, or is there any other way around? My visa expires soon and I would again have to apply for a visitor visa and come for an id check.

In fact I did call the GMC , they said that it is not mandatory to show ielts, any proof that I was involved with the language in the past two years would suffice, does anyone have any idea, because he told me to check the website, but I could find nothing related to it. If anyone has any knowledge about this kindly comment.
Thanks in advance.
