DIANA is now second favourite with bookies to win the contest, slipping from the pole position she has held in recent weeks.

On October 21, she became the bookies’ favourite to win after Simon Cowell said she was the one to beat after her showstopping performance on of Michael Jackson hit Man In The Mirror.

Odds on her to win were slashed from 5/1 to 11/4.

Now the odds for her as outright winner are still 11/4 with Ladbrokes and William Hill.

Both bookies have Alexandra Burke as the odds-on favourite with evens available at Ladbrokes and 11/10 at William Hill.
