Editing Ken Buchanan (section)

===World champion===
In September of that year, Buchanan travelled to [[Puerto Rico]], where he would meet [[Ismael Laguna]], the world lightweight champion from Panama, on 26 September 1970. Many experts believed [[San Juan, Puerto Rico|San Juan]]'s warm weather would affect Buchanan, but he upset those who thought that way and beat Laguna by a 15-round decision to become world's lightweight champion.<ref>[https://www.nytimes.com/1970/09/27/archives/buchanan-rallies-to-outpoint-laguna-for-lightweight-title-in-puerto.html "Buchanan Rallies to Outpoint Laguna for Lightweight Title in Puerto Rico"]. ''[[The New York Times]]'', 27 September 1970.</ref>

At that time, the [[World Boxing Association|WBA]] and the [[British Boxing Board of Control]] (''BBBC''), were in the middle of a feud, and Buchanan was not allowed to defend the WBA title fight in [[Great Britain]]. He finished 1970 beating Donato Paduano by a 10-round decision in a non-title bout on 7 December 1970.<ref>[https://www.nytimes.com/1970/12/08/archives/buchanans-speed-defeats-paduano-scotsman-gains-unanimous-decision.html "Buchanan's Speed Defeats Paduano"]. ''[[The New York Times]]'', 8 December 1970.</ref>

Buchanan defeated Rubén Navarro in Los Angeles on 12 February 1971, defended the WBA championship, and acquired the vacant [[World Boxing Council|WBC]] championship.<ref name="a">[https://news.google.com/newspapers?nid=2mus-XyGPC0C&dat=19710211&id=iyY-AAAAIBAJ&sjid=uUoMAAAAIBAJ&pg=5768%2C5632706&hl=en "W.B.C. say Fight is for title"], ''[[Evening Times]]'' (Glasgow), 11 February 1971.</ref><ref name="b">[https://news.google.com/newspapers?nid=GGgVawPscysC&dat=19710212&id=JpJAAAAAIBAJ&sjid=BKUMAAAAIBAJ&pg=4064%2C2232553&hl=en "WBC approve Buchanan bout"], ''[[The Herald (Glasgow)|The Glasgow Herald]]'', 12 February 1971.</ref><ref name="e">[[World Boxing Council]] Ratings (March 1971)<br />[https://hndm.iib.unam.mx/consulta/publicacion/visualizar/558075be7d1e63c9fea1a303?pagina=558a38ea7d1ed64f16ebabd4&coleccion= {{in lang|es}} "Clasificaciones de Marzo Según el Consejo Mundial de Boxeo"], [[United Press International|UPI]], ''[[El Informador (Mexico)|El Informador]]'' ([[Guadalajara]], [[Jalisco]], [[Mexico]]), 11 March 1971.

After that, Buchanan was allowed to defend the world championship fight in [[Great Britain]]. Buchanan defeated former world junior welterweight champion [[Carlos Morocho Hernández]] by knockout in round eight of a non-title bout, in [[Wembley]] on 11 May 1971.<ref>[https://news.google.com/newspapers?nid=GGgVawPscysC&dat=19710512&id=Oc89AAAAIBAJ&sjid=_UcMAAAAIBAJ&pg=3922%2C2282329&hl=en "Classic show by Buchanan"], ''[[The Herald (Glasgow)|The Glasgow Herald]]'', 12 May 1971.</ref><ref>[https://news.google.com/newspapers?nid=2mus-XyGPC0C&dat=19710512&id=4OdAAAAAIBAJ&sjid=Y6cMAAAAIBAJ&pg=6253%2C1773997&hl=en "Great Buchanan has the fans cheering"], ''[[Evening Times]]'' (Glasgow), 12 May 1971.</ref>
