The senior Crown prosecutor in the case of Daniel Pelka has said she is "satisfied" with the sentencing of Magdelena Luczak and Mariusz Krezolek.
Speaking outside court, Lisa Windridge said:
It has been very harrowing and emotional to everybody that has worked on this case, from the police investigators, to those at the CPS and the barristers.
All cases can be very harrowing, particularly on the public protection unit, but this case has particularly touched those of us who have been involved.
Questions have been raised over the murder of Daniel Pelka, after his mother and stepfather were jailed for 30 years today.
A couple have been jailed for a minimum of 30 years for murdering four-year-old Daniel Pelka, in March 2012.
A "callous and wretched" mother and her partner are facing life sentences for murdering systematically abused four-year-old boy.
