After Lucy Letby, the UK's most prolific baby murderer, was sentenced earlier this month, there has been a lot of discussion about what form the public inquiry should take.

The government has now decided that it should be led by a judge with full powers to force people to give evidence. That's what the families have been asking for and Health Secretary Steve Barclay has said he has listened to them - but that kind of inquiry is likely to take more time.

Today's Martha Kearney first speaks to Dr Stephen Brearey, who is the lead consultant at the neonatal unit at the Countess of Chester Hospital and who originally raised concerns about Lucy Letby in 2015.

She also speaks to Sir Robert Francis, who was chair of the inquiry which looked into the failings into care in mid-Staffordshire.
