The director of one of Scotland's leading theatre has announced he is standing down after an anniversary season.

Mark Thomson is to leave the Royal Lyceum Theatre in May next year, after the 50th anniversary season for the Edinburgh venue.

Thomson joined The Lyceum in 2003 and under his artistic leadership the company produced more than 90 productions of which 28 were world premieres.

He said: "I can't think of a more positive way to finish my time here at the Lyceum than celebrating its 50th anniversary season with the likes of Brian Cox and Bill Paterson, great Lyceum people like Tony Cownie, John Dove and Liz Lochhead and with exciting collaborations with the Lyric Hammersmith, Told by an Idiot and National Theatre of Scotland.

"It is so difficult to leave a place like this with its incredible, dedicated and skilful teams, creative buzz and intelligent audiences.

"However, it's absolutely time for a new adventure for me now just as I have always seen my time here as the constant refreshing of passion-led creative adventure for the artists and audiences in this extraordinary arena that celebrates theatre so vibrantly."

In October last year Thomson expressed his disappointment at a funding cut to the theatre by arts funding body Creative Scotland.

The Lyceum received a package of £3 million over three years - a reduction of 17.5 per cent.

He said: "It is a very damaging cut not only for The Lyceum but for producing theatre in Scotland.

"We are playing a vital role in sustaining a theatre industry in Scotland so this decision seems like a perverse punishment for acknowledged success. The Lyceum is now faced with re-thinking our business model in less than six months."

Shonaig Macpherson, chair of the Lyceum, said: "Mark has been a passionate and inspiring Artistic Director.

"His commitment to ensuring the company produced bold seasons of work, encompassing the great classics of the theatre canon alongside new plays commissioned by The Lyceum, provided our audiences with a rich repertoire of high quality theatre.

"Our recently announced 50th Anniversary Season is the embodiment of this commitment and is set to be a fitting testament to his vision.

"We will of course be sad to see Mark leave, but in announcing his decision now our succession plans should allow for a smooth transition into the next chapter of artistic leadership."

The search to find a new Artistic Director will begin later this month.

The theatre is expected to announce a successor by the autumn of this year.
