A motorist is due to appear at Norwich Crown Court on Friday where she will be sentenced for causing the deaths of two Sutton Bridge sisters.
Marie Easter (44) has admitted causing the deaths of Tamzin and Jessica Portor, aged ten and seven, by driving without due care and attention.

The girls, who attended Sutton Bridge Westmere Primary School, suffered fatal head injuries as a result of the incident.
Their father Alan and brother Liam were also travelling in the car at the time and they escaped with minor injuries.
Mrs Easter also suffered minor injuries.
