POPE Francis is considering making his first visit to Scotland to sign a charter against extremism.

The leader of the Catholic leader could be a surprise addition to an event at St Andrews University in September.

It would be his first visit to the UK in three years.

The Vatican has not confirmed he will attend the event but says it is “under consideration.

If he did attend it would be in a private capacity to attend an event and not a large-scale pastoral visit like the one made by Pope Benedict in 2010.
