TEN new art commissions, including work by Scottish Turner Prize nominee Christine Borland, have been announced for Edinburgh Art Festival.

The new exhibitions celebrate the tenth anniversary of the city's visual art festival, which runs from August 1 to September 1.

This year's festival commissions programme, titled "Parley", highlights art that generates and depends on dialogue.

Ms Borland's work will be at the burned-out Watchtower of the New Calton Burial Ground while, Krijn de Koning's first exhibition in the UK will "transform Edinburgh College of Art's iconic sculpture court into a specially designed platform for debate and discussion".

Two Parley symposium events have been specially conceived for de Koning's installation in Edinburgh College of Art's Sculpture Court by artists Ross Sinclair and Rachel Maclean.

Also in the programme is Peter Liversidge's Flags for Edinburgh project, which will encourage the city's institutions to replace their usual flags with a simple message of "Hello" for the duration of the festival.

Director of EAF, Sorcha Carey, said: "Our 2013 programme, the most ambitious to date, celebrates art's unique capacity to promote dialogue and debate.

"We are particularly excited that this latest edition sees leading and emerging Scottish and international artists collaborate across borders to make new work for Scotland's extra-ordinary capital city."
