It's still the first week of Jeremy Corbyn's life as Labour leader, but the honeymoon period is definitely over.
It's no secret that he's been upsetting the media - not least when journalists get hospitalised while reporting on him - and the same thing seems to be happening with his own party members.
Pundits and betting fans alike are now watching to see who will be the first to jump ship - and which party they will defect to?
Ladbrokes has run the figures for City A.M. and Rochdale MP Simon Danczuk - who this week challenged Corbyn over his refusal to rule out wearing a white poppy at Remembrance Sunday in November - is favourite to leave first, with odds of 4/1.
Next up is Barrow and Furness MP John Woodcock, with odds of 5/1. Birmingham Hodge Hill's Liam Byrne has been identified as the third most-likely to leave, with odds of 8/1.
But money is also going on some of Labour's more high profile - and identifiably New Labour - MPs. Leadership rivals Liz Kendall and Yvette Cooper are both thought likely defectors, as is former shadow business secretary Chuka Umunna, who resigned within hours of Corbyn's win. Tristram Hunt and Kate Hoey are also on the list.
Here's how the odds stack up for the first Labour MP out the door:
