Having learnt English as a foreign language, my knowledge of "profanities" is a bit lacunoso (patchy). Am I guessing correcttly that k**b stands for knob in the context of "Ms Burley was broadcasting live from Aberdeen when heckled and called one campaigner a 'k**b' on air" in this news article?

Yes it means knob. The Daily Mail thinks it might offend your Grandma if it prints the word in full

If you're not familiar with English profanities, might I humbly suggest that you peruse the classic reference work on the subject, Roger's Profanisaurus, published by Fulchester University Press.

And here's another one for you. Kay Burley = t**t.
