The line-up for this year's Glasgow West End Festival has been revealed – but organisers have warned it could be the last time the popular Festival Sunday remains free.

The event, which includes the crowd-pulling Mardi Gras-style carnival procession, as well as bands and stalls, will again take place in Kelvingrove Park on June 5.

It was switched to the park three years ago due to costs, after Glasgow City Council told organisers it was unable to continue to waiver its £1500 fee for closing the road.

However, festival director Michael Dale said the event, which attracts tens of thousands of revellers, could come with a cost to the public in the future.

Mr Dale said: "Our challenge is to raise more revenue going into the park.

"This may be the last year we can have a free event in the park. I think we are going to have to talk seriously about whether we charge.

"It is costing around £80,000. We just can't raise enough revenue and the costs are going up.

"In an ideal world I would charge everybody £1 to go into the park. That's not impossible. It could happen and it would still be excellent value for money.

"People like the parade in the park. Byres Road was very crowded. It is now a different kind of event."

Organisers will be asking for donations on the day this year.

And while Festival Sunday is one of the highlights, the festival will be the biggest yet, with 600 events taking place over for three weeks from June 3-26.

Musician Tommy Reilly, winner of Orange Unsigned Act 2009, will launch the 16th annual event on June 3 with a concert at Oran Mor.

The Cottier Theatre, which has just reopened after a revamp, will host the Cottier Chamber Music programme, a series of 23 early evening music concerts.

The Gibson Street Gala also returns on June 12 with music and entertainment.

As previously reported in the Evening Times, an outdoor cinema run by The Grosvenor will be set up in Kelvingrove Park from June 23-26.
