Kinnock broke the rules. He apologised.
Did he apologise? The Guardian -
"South Wales force criticised for tweeting disapproval of MP defying coronavirus rules." ...
"I felt that this was essential travel as I had to deliver some necessary supplies to my parents. I stayed long enough to sing ‘happy birthday’ to Dad, and then I was off. All the best, Stephen." ...
"Critics said the police were overzealous in publicly criticising the MP, as others warned they could could lose the respect of the public." ...
"The MP’s sister, Rachel, could also face admonishment from police after she tweeted that she had visited her parents to deliver a “cake, a crumble and a lamb curry!”
