Not forgetting her earlier oppositionin in June to what has now been set up:
At the start of the year, the government dismissed calls for a national inquiry, arguing it had already been examined in a seven-year inquiry led by Professor Alexis Jay.
But speaking to reporters on his way to the G7 summit, which begins in Canada tomorrow, the prime minister said: "I've never said we should not look again at any issue."
He added that Baroness Casey had originally thought a new inquiry was not necessary, but she had changed her mind having looked into it in recent months.
"She's come to the view there should be a national inquiry on the basis of what she's seen," Sir Keir said.
"I've read every single word of her report, and I'm going to accept her recommendation.
"I think that's the right thing to do, on the basis of what she has put in her audit.
"I asked her to do that job, to double-check on this.
"She's done that job for me, and having read her report… I shall now implement her recommendation."
He added that it "will take a bit of time" to set up the inquiry, but added that "it will be statutory under the Inquiries Act".
This means the inquiry will be able to compel witnesses to provide evidence., external
A senior government source said the inquiry would "co-ordinate a series of targeted local investigations".
This will include new local investigations, which will take place even if local authorities don't want one.
The local investigations will have the power to compel evidence to be given and witnesses to appear.
