At the request of Her Majesty's Government, a Spanish delegation met UK officials in February 1956 with a view to negotiating a social security agreement between the two countries to protect the benefit rights of migrant workers moving from one country to the other and to ensure that they pay into only one country's social security scheme. Negotiations ceased in 1960 and subsequently resumed again in 1971. The agreement with the Spanish Government was signed on 13 September 1974.
