Casting directors are snubbing British performers in favour of European rivals, an industry insider has revealed.

A talent agency boss received an email asking for clients to work on a project abroad, stressing: “FOR THESE CONTRACTS YOUR CLIENT MUST HAVE AN EU PASSPORT (UK PASSPORT NOT INCLUDED) OR HAVE RESIDENCY IN SPAIN OR GREECE.”

A message from Spotlight, a platform used by casting directors and which styles itself as “the home of casting”, looked to fill singing roles for a musical stage residency at two TUI Sensatori holiday resorts – and needed people who could work in Ibiza and Crete.

A follow-up email added: “Please ONLY performers with EU PASSPORTS – UK Passport does no (sic) count.

“If they have residency in Greece or Spain, great – please also highlight.

“If the clients you have submitted do not fit this criteria – PLEASE REMOVE!”

With ongoing uncertainty over a Brexit deal between the UK and EU, showbiz chiefs are taking no chances on Britons' eligibility to take long-term jobs on the Continent.

Apostrophe Talent director Pablo O’Hana, who received the email, said: “Brexit was always going to be a disaster, especially for freedom of movement.

“For the last five years, I have been warning about exactly this, but actually seeing it in my inbox sent a chill down my spine.

“This could be the end of British entertainment as we know it.

“We are being cut out, opportunities are moving elsewhere and how can we blame them?

“Who would risk hiring talent from a country so intent on driving itself off a cliff?

“How can casting directors and studios plan their productions when there is absolutely no direction or plan from the Government?”

A TUI UK spokeswoman said: “As Europe’s largest travel company we recruit our overseas team members from all over the world and have done for many years.

“We will continue to offer overseas opportunities for UK and EU passport holders.

“We work hard to be a diverse and inclusive business and will continue to do so.”
