This would still make sense, if the reporting tenses don't imply an element of time travel is required.
The date of writing this post is June 28th 2019.
This newspaper article was published on 26th June.
The story states the winner of the contest to replace Theresa May as UK prime minister will be announced on July 23rd.
But the headline states:
'New British PM named on July 23'A reader has every reason to get tense, with this lack of attention to tense matters.
Or is this a prime example of a future, past impossible tense?
Cue in the tension headache!
