The mother of murdered British teenager Scarlett Keeling, Fiona MacKeown, 44, will appear at the trial of two men accused of raping and killing the 15-year-old on a beach in Goa.

According to the Daily Express, she was summoned to the children's court in the same region in which her daughter's died - after fighting for a full investigation when police initially suggested Scarlett accidentally drowned.

MacKeown faced allegations of negligence for leaving her young daughter alone while she went travelling to neighbouring Karnataka.

Scarlett's bruised body was found on the beach in Goa in February 2008 where she had gone on a holiday with her family.

The trial of accused Samson D'Souza, 30, and Placido Carvalho, 42, has faced extensive delays.

Counsel to the Central Bureau of Investigation, S R Rivonkar, said he expected it to be complete by the end of the year.

The duo, charged with culpable homicide, sexual assault, outraging modesty and destroying evidence, were arrested a month after Scarlett's death.

D'Souza and Carvalho, who are both on bail, deny the charges. (ANI)
