Journalist does not come under the protected title legislation in The UK.   Press credentials may be required for access to certain places and information, but the title is a free one.

Michael has every right to call himself a journalist. If I were so minded, I could too.

There again, I told Keith I had decided to call myself a historian (I have written and had published a couple of potted histories, mainly around six sigma and how it was introduced and adapted, in order to inform future realisation, but there you go. I am a published historian.)

So... Using Keith's provisos;

I am living. I am most certainly eminent.

Check. Your move.

(Dunno about journalist though. Writing against deadlines is hard work and I am in the Douglas Adams camp in that regard.)
