ITV must be primed for complaints this evening after Britain’s Got Talent judges Amanda Holden, Alesha Dixon and Simon Cowell decided to wear outfits slashed to the navel.

The trio follow in the footsteps of Rita Ora whose January appearance on BBC’s The One Show wearing a similarly plunging garment elicited more than 400 complaints to the broadcaster and 28 to media watchdog Ofcom.

Holden wore a Disney’s Frozen-inspired gown by Tony Ward while Alesha chose a sparkly lace number in black with slits down the front and on one side. Cowell, who is famous for the unique way he wears trousers, shocked viewers by eschewing his usual pairing of black slacks and white shirt by opting for a grey suit - and he appears to have left an extra button on his shirt undone this week.

Viewers have already taken to Twitter to complain about the trio’s sartorial choices with only David Walliams (attired in a tuxedo and bow tie) apparently remaining unscathed.

Jules O'Dwyer and her dog Matisse won the competition, beating magician Jamie Raven and Welsh choir Cor Glanaethwy in the final three.

The duo will perform in this year’s Royal Variety Performance and take home a cash prize of £250,000.
