Mail On Sunday: Nigel Evans' Arrest

Haven't seen all of Sunday's front pages yet, but so far the Mail is the only paper to put in their headline Nigel Evans was arrested over an allegation of "gay rape" - a loaded term no-one uses anymore.
I think they mean "male rape" - others thought "rape" sufficed.
Whilst Evans is gay - he came out in 2010 in... the Mail On Sunday - the inclusion of the word here seems at best odd/off. 
The MoS also missed out a word present in other headlines... "Tory".
Must be difficult to know which words to prioritise with a story like this, eh?
Anyway, let the feeding frenzy begin.

Update: The Sun Sunday have used the same terrible terminology in their, err, "exclusive".
