Saturday saw the latest live show and eliminations as four contestants were cut.
And Mo has returned as The Voice UK favourite to win after an impressive quarter-final performance saw his odds slashed in half to 2/1 from 4/1 with bookies Boylesports.
His fellow Team Jennifer teammate Jamie Miller, who overtook Mo in the betting just last week, has been pushed out to the second favourite at 5/2 after surviving the public vote.
Meanwhile, Team Tom’s duo Into the Ark are next in the betting at 11/2 having shortened slightly from 6/1 after their rendition of Nick Jonas’ ‘Jealous’.
Jason Jones is leading the charge for Team Will at 6/1 after winning the Black Eyed Peas star's fast pass while Max Vickers is Team Gavin’s strongest act at 8/1.
Making up the rest of the semi-finalists left in the show at this stage are Truly Ford (12/1), Craig Ward (16/1) and Michelle John (20/1)
Aoife Heffron, Spokeswoman for BoyleSports commented: “Mo was briefly knocked off his perch at the head of the betting by Jamie Miller, but after his jaw dropping quarter final performance of Bob Dylan ‘Knocking On Heaven's Door’ we had no choice but to slashed his odds to 2/1 from 4/1.”
She added: “Jamie Miller remains Mo’s biggest threat at 5/2 and he is also our biggest threat as he poses a large liability should he go all the way and win.”
