A huge audience tuned in to see Attraction crowned winners of Britain’s Got Talent 2013 on Saturday night.

According to overnight figures an average audience of 11.1m – including those who watched on the catch-up service ITV+1 – tuned into the two and a half hour extravaganza as eleven acts battled it out for the chance to appear at the Royal Variety Performance.

And the peak audience was even more impressive, with a massive 13.1m viewers watching the show at the halfway mark.

Meanwhile the ratings topped the 12.5m mark towards the end of the show when the results were announced.

Although the figures were down slightly on the 2012 final, which pulled in 760,000 viewers as Ashleigh and Pudsey swept to victory – it was still the most-watched show of this year’s series.

And they accounted for 50 per cent of the viewing audience at that time – with BBC One only managing to score around 3m viewers for any of its shows during that time.

Saturday’s final attracted some unwarranted attention after a stage invader – later revealed to be musician Natalie Holt – walked on while brothers Richard and Adam Johnson were performing and pelted Simon Cowell and the other judges with eggs.

The 30-year-old viola player later apologised, saying “I’ve never done anything like this before and in hindsight I realise it was a silly thing to do.”
