The disappearing flag and the unfortunate halo. The latter is presumably the result of some slightly clumsy lightening of the photo (though if it was another party’s leader in the photo, you can imagine the sort of intemperate comments that would appear from SNP supporters about how this was the lowest and most desparate acts of evils since the same party leader ate babies for breakfast yesterday). But as for the former? Very hard to see any explanation other than a mix of pettiness and silliness.
