Sinn Féin has said the Irish Government needs to appoint a new ambassador to Egypt as soon as possible.
It is after MEP Lynn Boylan from the party raised fears that Irish citizen Ibrahim Halawa could face tougher prison conditions if Ireland does not maintain diplomatic pressure to have him released.
The 19-year-old from Firhouse in Dublin is approaching the two-year anniversary of his arrest in Egypt, and is still awaiting trial.
The government has said it determined to secure his release, but that it cannot interfere with the judicial system in Egypt.
