The medals on display in Major Walsh's home are (left to right) the General Service, South Atlantic, Gulf and Kuwait Liberation. The Kuwait Medal is displayed separately from the others because in the UK it is not authorised for uniform wear, but may be kept as a memento.
The tellers outside the polling station at the by-election are shown, not only with party political leaflets, but actually trying to hand them to voters. This would never be allowed under UK voting law.
