U.K gambling laws are easily accessible through the Gambling Act of 2005. This Act basically states the legalization of gambling in the U.K and the fact that U.K citizens do not pay tax on their gambling winnings. Do check up now and then on these laws, as they can change from time to time.
The U.K government is quite determined to promote both the pros and cons of gambling and also try to keep the nature of gambling free and fair. The U.S differs somewhat in their gambling policies, as they still follow the 1961 Act that was implemented when gambling first became legal in the U.S. Often the U.S laws can be a little harsher than the U.K’s, as they tend to favour the casinos rights over those of the players.
Remember that whilst there are laws in every country about how that particular government believes gambling should be controlled, the laws are primarily there to enforce licensed operators.
