Two people have been charged in connection with the death of a two-year-old girl who had ingested methadone.
Barry Jones, 41, and Michelle King, 29, both of Jameson Street, Blackpool, were charged with causing or allowing the death of a child by means of an unlawful act contrary to Section 5 of the Domestic Violence Crime and Victims Act 2004.
They have been remanded in custody and are due to appear at Blackpool Magistrates' Court tomorrow, Lancashire Police said.
The force said that toxicology tests showed Sophie Jones had ingested methadone, but that the cause of her death was not yet known.
The charges come after Sophie was taken to hospital from her home in Blackpool on Tuesday night. She died later at Blackpool Victoria Hospital.
