'Britain's Got Talent' narrowly beat 'The Voice' in Saturday's (28.04.12) ratings.

Bosses on the ITV1 talent show - which is hosted by Ant and Dec and judges by Simon Cowell, Amanda Holden, David Walliams and Alesha Dixon - were thrilled to see the show peak at 10.7 million viewers and average 9.4 million through the episode.

In contrast, 'The Voice' - which saw contestants from Sir Tom Jones and will.i.am's teams perform live for the first time - peaked with 10.3 million and averaged 9.3 million.

An ITV spokesperson said: "'Britain's Got Talent' is packed with thrills and spills, tears and laughter and we are delighted that it consistently continues to be such a firm favourite with viewers."

While bosses are said to be worried that 'The Voice' has lost viewers, they are not surprised by the drop because a similar slump occurred on the US version of the show once the tension-filled blind audition stages came to an end.

A source told The Sun newspaper: "In America The Voice's ratings dipped by 40 per cent when the live shows started. Luckily The Voice in the UK has only lost around ten per cent.

"But it's still a worry -- and it's being blamed on the red chairs.

"Now we're in the live shows the 'will-they-won't-they?' turnaround gimmick is all over.

"Viewers loved the theatre of the chairs, the buzzers and the new faces."
