Detective Inspector Paul Greatorex said: “We are continuing to work with colleagues at the fire service to investigate this dreadfully sad incident which has resulted in a father and daughter losing their lives.
“Extensive enquiries have been ongoing since yesterday and we have been working to locate and support relatives of the victims both here and outside of the UK at what is clearly an awful time for the family.
“While our enquiries remain ongoing we do not believe there are any suspicious circumstances regarding the cause of the fire and will be preparing a file for the coroner in due course.
