English Court system (modern day) conviction and/or sentencing

[goldvermilion87]

I've done a bit of research, and I want to have one of my characters convicted of voluntary manslaughter in England.

First of all, to check that -- does voluntary manslaughter sound reasonable when the character did not premeditate his act, was under the influence, and had been provoked?  I was reading around and that seemed to fit reasonably well, but I was looking at the online CPS guidelines and I might not be translating them well from legalese in to what actually happened. :-)

Secondly, does anyone know how the conviction would actually be phrased?  "This court finds you guilty of voluntary manslaughter" ?  Something more wordy?  Something entirely different?  I've been searching sentencing guidelines, looking for court transcripts, and even attempting to watch episodes of Law and Order UK, all to no avail.  So any help would be appreciated.

Finally, does seven years sound reasonable as a sentence?  I got that from the sentencing guidelines I found online.  I actually don't really care how long it is for the purposes of the story, so if anyone can convince me that some other length of time is better I'm game.

Thanks in advance for all your help!

EDIT:  Thanks for the help so far.  :-)

I realized I hid my main question in the body of a paragraph, so just to make it clear, what I'm mainly interested in is this:

How would the actual conviction be phrased? Is there a formula that the Judge must/is likely to use?

Thanks!
