I suspect Farage would promise anything which might bring him votes. There were murmurings of this from the Tories pre-2010 election, but that's the last we hear of it. Sorry, but IMO Farage is just a BS merchant - I don't believe a word he says.
They
all promise anything and they have
all lied their teeth off so why not give Nigel a chance?
As for UK shooting, it is certainly not safe right now, just look at that oaf Salmond and his chum McAsskill in Scotland - they are using an airgun ban as a votecatcher.
