Do u have sense BBC (& CNN)  have diluted News in lock-down? BBC fills its site with photos, not content & says almost nothing about brexit?

I believe BBC tends to give a balance report of news.

Lots of things have been written and said on Brexit under the BBC umbrella.  If you want more news on it, there are other U.K. orientated news websites.  

What kind of news would you like? The silly 'gossip-like' stuff given to us by ITV in the early evening - and what has CNN have to do with Brexit. As they're based in America, they have more important (and more violent) things to deal with.

I watch\log on BBC and they report any news about Brexit when it happens. The last big piece of news was the finalization of the Brexit deal just a couple of days before the ending of the transition period and the termination of our membership with the EU. The BBC reported it pretty thoroughly IIRC.

Evidently, you haven't been in the UK lately. All the news reports there pretty much only talk about COVID or Brexit.

Not really.  Talking EXCESSIVELY about Brexit is like beating a dead horse, but I have seen at least two stories about it in the last 2 weeks.

I don't sense that at all with the BBC and I know nothing about CNN. Brexit was prominent on the BBC until the transition ended and for a few weeks afterwards when the shortcomings in the Brexit agreement became apparent. Now it has taken a back seat to COVID. The BBC has, like other news sites, become more reliant on videos with less text and photos over the past few years, possibly due to the switch to HTML5.

'Brexit' is not news, it is done.   This is 2021.

Don't know what you are watching but there is plenty about Brexit, 

although now it has happened it is not much of a story.

The BBC seems to be only reporting certain things. Issues like the fallout from Brexit, including the massive issues in Northern Ireland, are oddly missing.
