Menswear chain Roger David will embark on an immediate national closing down sale that could see the business shut down shortly after Christmas after being placed in voluntary administration.

The privately owned company, which operates the Roger David, RDX and Stray brands, called in administrator KordaMentha after being unable to cope with an influx of international competitors and the "rapid evolution" of online shopping.

KordaMentha said in a statement that administrators Craig Shepard and Leanne Chesser would immediately begin a national closing down sale "to clear stock and raise as much money as possible for employees and other creditors".

"Stock will be marked down to clear," the statement said. The company's website was advertising "50 per cent off everything" on Thursday afternoon.
