Meghan Markle's estranged half-brother has said Prince Harry's days as her husband are numbered as his younger sister's last marriage only lasted two years.
Thomas Markle Jr, a 55-year-old window fitter from Oregon, claimed Meghan's marriage to Prince Harry is doomed in a new trailer for Australia's Big Brother VIP.
In the trailer, Markle Jr alleges Meghan 'walked all over' her first husband, American film producer Trevor Engelson, but it's unclear if he has any knowledge of the circumstances of their split.
In the trailer, Markle Jr says: 'The guy that she was married to the first time - she just walked all over him and dumped him.'
In response to another housemate who says that sounds 'cold-blooded', Markle Jr nods before adding: 'Harry's on the chopping block next.'

Since his selection for Big Brother was announced, Markle Jnr has made several comments on his sister and her marriage to Prince Harry.
Back in August, in another trailer for the show, he revealed he warned Prince Harry his 'very shallow' sister would 'ruin' his life and had abandoned her 'own flesh and blood' as he entered the Celebrity Big Brother house in Australia.
