Tributes have been paid to a "trailblazing" lawyer at a top immigration law firm who died after falling under a Tube train.
Sonia Burgess, 63, known professionally by her legal name David, was struck by a train at King's Cross station during the Monday evening rush hour.
Nina Kanagasingham, 34, of Chichele Road, Cricklewood, north-west London, has been charged with murder and appeared at City of Westminster Magistrates' Court. She was remanded in custody to appear at the Old Bailey on Monday.
The family of the solicitor, who have asked for her to be referred to as Sonia, said in a statement: "Sonia (David) was a loving and wonderful person and will be missed deeply. We would appreciate being given space to come to terms with our loss."
Ms Burgess, who had worked in immigration law since the 1970s, leaves three adult children, two daughters and a son.
A spokesman for Luqmani Thompson and Partners in Wood Green, north London, the law firm where she worked as David Burgess, said: "We are immensely saddened by the death of David Burgess, an enormously talented practitioner, an inspiration to a generation of lawyers practising in this field, and a great friend."
Investigating officer Detective Superintendent Ashley Croft said: "We would like to express our condolences to Sonia's (David's) family following this tragedy.
"Family liaison officers are working closely with Sonia's family, providing them support and assistance during this difficult time."
A British Transport Police spokesman said: "Sonia, a solicitor, had two identities, David and Sonia, that were both well-known to her family, friends and work colleagues."
Ms Burgess's family, including her children and former wife, said they did not wish to make any further comment.
