A woman games teacher faces a jail sentence after admitting sexual activity with a pupil who she taught at an all girls private school. 

Emily Fox, 26, pleaded guilty to four counts of sexual activity with a child while in a position of trust.

The offences took place between August 4, 2012 and August 3, 2013 when Fox was a teacher at the Royal Masonic School for girls in Rickmansworth.

Fox of Alfred Steet, Bath, admitted the charges at St Albans crown yesterday. The case was not opened by prosecutor Sally Mealing-McLeod.

Defence barrister Dee Connelly asked for the case to be adjourned for a pre-sentence report. She said the sentencing guidelines starting point for the offences was four years in jail with a range of three to seven years.

Judge Michael Baker QC adjourned sentence until September 5 and granted Fox bail. He said she must now register as a sex offender. 

He said bail should continue with the condition that Fox does not attend the Royal Masonic School and has no contact with anyone aged under 16. 

The girl cannot be identified, but Judge Baker lifted a contempt order that had prevented publication of the defendant's name and the name of the school. 

The judge said: "It is clearly in the public interest to identify the school as well as the defendant. It is, to my knowledge, by no means a small school. I don't see how the identification of the school leads to the identification of the child."
