The UK Government signed the below Convention in March 1986, and it came into force July 2000.
Despite this the number of animals being experimented on in any given year in the UK is increasing and not decreasing as should be. The UK government has failed to honour this agreement.

European Convention for the Protection of Vertebrate Animals used for Experimental and other Scientific Purposes
Summary of the treaty
The Convention is designed primarily to reduce both the number of experiments and the number of animals used for such purposes. It encourages Parties not to experiment on animals except where there is no alternative. All research into alternative methods should be encouraged. Animals to be experimented on should be selected on the basis of clearly established quantitative criteria and must be well cared for and spared avoidable suffering whenever possible.
To this end, the Convention lays down a number of principles which are to be considered only as a starting point. The Parties meet regularly to examine the application of the Convention and, if appropriate, to extend or strengthen its provisions.
