Visa status
The US and the UK permit each other's citizens to travel without visas to each other's country for the most part. This is by treaty and I understand that if a country like the UK arbitrarily starts excluding people, that treaty falls out and visitors on quick business and tourist trips (of which there are quite a lot from the UK as you're traditionally a huge investor in the US) would have to start getting visas to enter the US.
This is unlikely to happen if it's just Mr. Savage excluded but if this is the start of a new trend towards political intervention in american affairs by 'shaming' medium sized US political players whose politics are non-violent but not favored by Her Majesty's current government then eventually there will be an unpleasant reaction.
Mr. Savage is not the first to land in this boat; MP Wilders precedes him. It is a stupid policy and I hope Her Majesty's next government comes to its senses.
