To no avail, in 1948 Negrín spoke out in favour of Franco's Spain's participation in the post-war Marshall Plan, which was opposed by the Spanish Republican government in exile. In his opinion, the economic assistance to Spain was indispensable to the economic recovery of Europe, while its exclusion could have no other result than to increase further the sufferings of the Spanish people.
