Well the report referred to by the poster at 09.34 AM was from the far-right Daily Express, one of the tabloids miffed by being blamed for propagating the mixed messages that have been coming out lately apropos of relaxing the lockdown, so we can take their gloss on the story with a bucket of salt. Said poster even copied and pasted the headline, neglecting to correct the Express's misspelling of "responsibility." I've watched the clip twice and can see no trace of Ashworth having been "stunned" by Marr's rather circuitous questioning.

And this beauty:

"Pretty bad   accusation when it comes from a doyen    of the left like red marr.   I guess the BBC    is finlly realisinng their PARTISAN days are numbered." [sic]

...is definitely one for the archives! :-)
