It comes after the two candidates for the Conservative leadership raised questions about the new charges.
Robert Jenrick suggested that information was being “concealed” from the public.
“We were told for months that this was not a terror-related incident, and yet we have learnt that this individual, the suspect, was allegedly reading al-Qaeda manuals and had access to dangerous substances like ricin,” he said.
“Given the scale of public interest, I think it is an important question to be asked, why was this information not put into the public domain sooner? So I’m asking the public authorities and the prime minister, what did they know, when did they learn it, and why was the decision taken not to be more honest and transparent with the public.”
Meanwhile Kemi Badenoch has suggested there are “serious questions to be asked of the police, the CPS and also of Keir Starmer’s response”.
She has not elaborated on what those questions are, suggesting they should be asked in Parliament.
The police say it is “certainly not the case” that they have been keeping things from the public. It would be highly unusual for them to release details of a live police investigation.
The CPS suggest it has taken time to bring the charges because this was a “lengthy and complex investigation”.
