There were gasps from MPs during the Prime Minister's statement on the Hillsborough report as the truth was finally revealed.
One MP, Alison McGovern, who represents Wirrall South, was in tears. Others were clearly emotional and upset.
Many hadn't expected David Cameron to make such an apology today. But he did, using words such as 'profoundly sorry'.
I asked his spokeswoman whether he was shocked when he'd read the report this morning. "Of course," was the reply.
And so Mr Cameron revealed he'd already asked the Attorney General, Dominic Grieve to consider today's findings and decide whether to apply for the High Court for new inquests.
I think it's clear the PM expects and wants that to happen. That could of course pave the way for prosecutions. Nothing is off the table now.
