On education, two of the three stories you listed broke after 9am. Clegg made his comments on LBC and the league tables weren't published until 0930.
The immigration story is interesting - yep, that could have been a contender.
EU/Davos - really, if you wanted that, Radio 4 isn't it? Ditto Israel.
Again, there's been plenty of "dumbing down" stuff on this thread today. It's quite simple. Five Live is essentially a tabloid station. That's it. Who's pretending otherwise?
not sure quite what you mean by "plenty of dumbing down on this thread" it's been quite talkative & interesting mostly and seen no evidence of any dumbing down from anyone
