The objective of this study is to explore the facilitating factors and opportunities that can promote the implementation of local food purchase (LFP) in Spanish school meals in the opinions of key informants (IK). A qualitative study was carried out based on in-depth interviews with 14 KI capable of influencing Spanish food policy (Representatives of consumers and/or producers, representatives of organizations that promote LFP, and representatives of the government and/or academics). They were asked about opportunities and facilitating factors for implementation of LFP. Interviews were recorded and transcribed. A qualitative content analysis was carried out with Atlas ti. The analysis of the interviews produced two categories that include factors that- in the interviewees’ opinions- can promote LFP (social fabric and policy) and three categories that bring together the factors that represent opportunities for implementation in school meal programs in Spain (the policy agenda, regional characteristics and regional context). The overlap between social and political demands were considered to be facilitating factors for LFP. Furthermore, in the opinions of KI, the presence of health and sustainability issues on the public agenda, the existence of a structured productive system and political changes represent an opportunity to implement LFP.
