Pope should meet victims: Ritchie
The Pope is in London on Friday for the second day of his visit to the UK.
He will meet the Archbishop of Canterbury and address MPs and lords in Westminster.
SDLP leader Margaret Ritchie will be amongst those to hear Pope Benedict speak. She said he must make time to meet those who were abused by priests.
"The Pope must as a matter of urgency meet with the victims, who have been subject to such grave injustices," Ms Ritchie said.
"There is absolutely no doubt about that and the Pope must dictate I suppose in very unequivocal terms that those actions carried out by people, by priests and others, were totally wrong."
She added: "I am delighted that the Holy Father is visiting Britain and I would hope that this trip is a forerunner to a papal visit to the island of Ireland in the near future."
Pope Benedict will meet school children and students to celebrate Catholic education and will then join the Archbishop of Canterbury at Lambeth Palace.
He will then travel to Westminster Hall - the place where Sir Thomas More was tried in 1535 for showing allegiance to the Pope .
Pope Benedict will deliver a keynote speech to MPs, Peers, and former Prime Ministers.
Afterwards the Pope will join other christian leaders at Westminster Abbey.
