An MP has written to the head of British Transport Police to seek "long awaited answers" over the Croydon tram crash which killed seven people.
Another 62 people were injured, 19 seriously, on 9 November 2016.
Two-and-a-half years on from the crash, Croydon Central MP has expressed victims' families "growing frustration" at the pace of the criminal investigation.
The BTP say the investigation into the fatal crash is still ongoing.
In a letter to Chief Constable Paul Crowther, Ms Jones wrote: "Having met with constituents who lost family members in the tram crash, I know there is growing frustration with the long wait for answers.
"One family’s lawyer has branded this a 'national disgrace'. As you will know, until the result of the criminal investigation, no coroner’s inquest can take place."
