Radio 4. News reader stumbles, rate thereof.

[cumfy]

I've become increasingly bemused at the rate of announcer and news reader errors on Radio 4.
What seems to happen is that the presenter reads from a script with errors, which trips them up.
80% of the time they appear to pre-empt the error with a bit of pausing but 20% or so get through and in just the last couple of days such gems as:

"forced convection" being corrected to "forced confession"
"MS" being corrected to "estimated"
"boiling point point"

have been blurted out.
I sincerely do not believe that these people cannot read their scripts/autocues.
So what's going on ?

How are these scripts so in error and/or why do the presenters not read them through prior to reading out ?

Haven't they just done away with lots of the professional announcer/newsreaders? This may mean that lots of the people now doing these segments aren't used to it and are nervous.

It's been getting worse over the last 4-5 years.

And it's definitely the scripts, not the announcers that appear to be the problem.

spellcheckers...

Charlotte Green has retired as a BBC Radio 4 newsreader after 25 years!

Charlotte and her colleague Harriet Cass opted for voluntary redundancy owing to reorganisation. Green's final bulletin was the 6 o'clock news on Friday 18 January 2013.

Shame on the BBC...
