The mum of a young woman who died suddenly has appealed for help in finding out what happened to her.
Natalie Lewis-Hoyle was the daughter of Councillor Miriam Lewis and Chorley MP Lindsay Hoyle.
Mr Hoyle posted a short tweet on Saturday afternoon, paying tribute to Natalie.
He wrote: "I am truly devastated by the death of our beautiful daughter Natalie. Our family will never be the same without our loving granddaughter, sister & aunty. Thank you for the kind support we've received it is overwhelming."
Her mum has urged anyone with information about her sudden death to get in touch with Essex Police.
"It is with unbearable sadness that I have to announce the sudden death of my beautiful, much adored daughter Natalie," the Maldon district councillor said on Facebook.
She asked anyone contacted by "Natty" on Thursday night to get in touch with police, and said her daughter's mobile phone was missing - possibly left on a train from London Liverpool Street to Ipswich.
She added: "Natalie is my only child, my mini-me. Please help me find out what happened to her in the hours before her death."
Dozens of people, including MPs, shared their condolences via Twitter.
Preston MP Mark Hendrick tweeted: "So sorry to hear this Lindsay. I cannot begin to imagine how you feel."
Morecambe and Lunesdale MP David Morris added: "So sorry to hear this awful news Lindsay. My thoughts are with you and the rest of your family at this sad time."
