The Journalism Foundation is hosting a gala event to raise funds to continue its support for free and ethical journalism around the world.

Among the beneficiaries will be the foundation's global projects, including the establishment of a college of journalism in Tunisia and a programme to train journalists in South Sudan.

Broadcaster Richard Bacon will host the evening, which will also feature Alexander Armstrong, Tim Minchin and ventriloquist Paul Zerdin. Mark Hix will be doing the cooking.

The event, billed as A Priceless Evening, will take place next Tuesday (22 May) at the London auction house Phillips de Pury. High profile media and PR figures are expected to attend along with people from the worlds of arts and entertainment.

The night will culminate in an auction conducted by Simon de Pury. On offer will be several lots, including lunch with Gillian Anderson cooked byGordon Ramsay at Claridge's, tickets and flights to the world premiere in New Zealand of The Hobbit and a dancing date with Nancy Dell'Olio.

The Journalism Foundation was launched in December 2011 with backing from the Lebedev family.

Its chief executive, Simon Kelner, said: "Our mission is to develop and sustain free and ethical journalism by supporting media projects that have a positive effect on people's lives.

"We hope that the generosity of those attending the evening will help us fund the projects that further these aims."
