"There are no words to even begin to describe the crushing pain and emptiness that is left in our hearts.

"Our family, together with Andrei, are deeply touched and eternally grateful for the unimaginable efforts and never-ending dedication provided to her and us by the entire medical personnel of each and every hospital involved. Their kindness and empathy are beyond compare.

"We would not have been able to live through these trying and tragically hurtful weeks without the support of the Metropolitan Police, the UK Government and every department involved.

"Our hearts and love go out to our two Family Liaison Officers, Detective Sergeants Tony De-Wilde and Geraint Jones, who stood beside us every single step of the way. You were our lifeline and we will never be able to thank you enough."

Many politicians and others have given their condolences to the family, and expressed their sorrow over her death.
