Musician and humanitarian activist Bob Geldof and bestselling author Marian Keyes have been presented with honorary doctorates at the University of Limerick.

The Honorary Doctorates of Letters were presented today as part of this week’s graduation ceremonies at the university.

UL bestows the honorary doctorates on "individuals who have shown outstanding achievement" in the arts, sciences, business, industry, the professions, sport, social service or public service.

President of UL Dr Des Fitzgerald pointed out that Marian Keyes has "strong connections" with the region.

Her mother Mary is from Co Clare, while her late father Ted was from Limerick city. Marian herself was born in Limerick and spent the first year of her life on St Patrick’s Road in the city.

The author has shown commitment to activism, the ceremony heard today. She donated all of the royalties from her bestselling book Under The Duvet to the Irish Simon Community.

Boomtown Rats singer Bob Geldof is best-known for humanitarian work with Band-Aid and Live Aid.

"Bob has lobbied politicians and world leaders of all political hues in his herculean efforts to resolve global inequality and poverty," said Dr Fitzgerald.

"In 2017, he handed over the entire archive of the Band-Aid Trust to the National Library of Ireland; this will be a major resource for postgraduate students and academic researchers," added the UL president.

Both Keyes and Geldof have been guests at UL’s Frank McCourt Creative Writing Festival.

Local band The Cranberries is due to be honoured by the university later this week.
