PM 'delighted' to work cross party over online safetypublished at 12:22 British Summer Time 20 October 2021
For his final question, Starmer turns to calls from MPs to close down anonymous accounts on social media - but he says such a measure would not have prevented the murders of Jo Cox, PC Keith Palmer nor Sir David Amess.
"If we are to get serious, we need to stop online spaces be safe spaces for terrorism," he adds, saying "unaccountable, arrogant social media companies" needed to take responsibility.
The Labour leader calls on the PM to work cross-party with Labour on the problems.
Johnson says he would be "delighted" to join Starmer in tackling online harms and extremism, saying "that is what the government is doing".
He also claims the Conservatives are investing "record sums" in counter-terrorism.
But he again calls for Labour to support measures to stop the early release of extremists.
