Poppi Worthington: timeline of key events surrounding toddler's death

Poppi Worthington died in 2012.

A timeline of events following the death of 13-month-old Poppi Worthington - whose second inquest is due to finish today.

Poppi Worthington dies suddenly aged 13 months after she collapses at her home in Barrow-in-Furness, Cumbria, and is rushed to hospital.

Poppi is buried after the coroner releases her body.

A full post-mortem report indicates the cause of death is unascertained.

Poppi's parents are arrested and formally interviewed for the first time.

Poppi's father, Paul Worthington, is questioned on suspicion of sexually assaulting his daughter - an allegation he denies.

A fact-finding judgment on the circumstances of Poppi's death is delivered in private as part of family court proceedings involving other children in the family.

Its publication is delayed in case it prejudices any criminal trial.

HM Coroner for South Cumbria, Ian Smith - now retired - holds an inquest at Barrow Town Hall and takes just seven minutes to declare her death as unexplained after stating he was satisfied to rely on the findings of the private fact-finding judgment.

The case is not listed in Poppi's name but as "a child aged 13 months".

HM Senior Coroner for Cumbria, David Roberts, confirms he will ask for a fresh inquest.

It's in a written reply to lawyers representing various media groups who argued the October hearing was insufficient and therefore unlawful.

Cumbria Police announce no charges will be brought against anyone over Poppi's death after they had previously passed a file to the Crown Prosecution Service for its consideration.

Paul Worthington is granted a review of the March 2014 medical evidence, which further delays publication of the original fact-finding judgment.

High Court judges order a fresh inquest into the youngster's death after the first hearing was deemed "irregular".

A hearing reviewing the medical evidence from the March 2014 court proceedings gets under way in Liverpool.

Ahead of the hearing, Mr Justice Peter Jackson (now Lord Justice Peter Jackson) releases parts of his original fact-finding judgment which reveal that Cumbria Police did not conduct any "real" investigation into Poppi's death for nine months despite a senior pathologist raising concerns the girl's injuries were caused by "a penetrative sexual assault".

On January 19 2016 , the judge announced his findings that - on the balance of probabilities - Mr Worthington had sexually assaulted Poppi shortly before her death.

The Crown Prosecution Service says there is insufficient evidence to charge Paul Worthington with any offence over his daughter's death.

The CPS states that its decision not to charge was correct following an independent review of the evidence, prompted by a request under the victims' right to review scheme.

The Independent Police Complaints Commission (IPCC) finally publishes its 2015 findings into the initial police probe over Poppi's death.

It finds the approach of senior detectives was "unstructured and disorganised" and that there were enough grounds to make an arrest on the day of Poppi's death.

On 27 November 27, 2017, the second inquest starts at County Hall, Kendal, and hears more than three weeks of evidence.

HM Senior Coroner for Cumbria, David Roberts, is due to give his conclusions today.
