So Mr Cummings has the right to break lockdown because of an allegedly autistic son? Some 2000 autistic children & young people are locked away from their parents in care settings during lockdown, in a system he has helped craft.
Right here, right now. https://www.parliament.uk/business/committees/committees-a-z/joint-select/human-rights-committee/news-parliament-2017/detention-learning-disabilities-autism-young-people-report-published-19-20/

This is the Parliamentary report. This is what Mr Cummings and team have been presiding over.
One rule for him, and another for everyone else?

Those parents of autistic young people would love to be able to care for their son or daughter right now in lockdown. Would love to be able to hug them, to share time with them as a family, together again. Safely & in a well supported way.
But this horrific system exists instead

So, I don't buy the 'poor autistic child' stuff. At all.
I visit the autistic young people kept in effective cells and fed through a hatch, often with their parents forbidden to visit them.
That's the reality of how much his Government cares about autistic young people.
