'those of us who want to discuss the issue of Johnson's potential downfall get on with it'
There's not much to 'get on with' is there until we know the actual facts that Gray will establish.
Johnson still seems very popular from what I've seen on sm. Yes Twitter isn't representative of the nation but many intelligent folk do seem to understand they've got the big things right like jobs, furlough, vaccines and the economy, whilst perhaps being a bit lax regarding workplace eating and drinking arrangements.
