Question: Who won a more prestigious prize, Hugh MacDiarmid or Harold Pinter?

<P0-S0> The PEN Pinter Prize and the Pinter International Writer of Courage Award both comprise an annual literary award launched in 2009 by English PEN in honour of the late Nobel Literature Prize-winning playwright Harold Pinter, who had been a Vice President of English PEN and an active member of the International PEN Writers in Prison Committee (WiPC). <P0-S1>  The award is given to "a British writer or a writer resident in Britain of outstanding literary merit who, in the words of Pinter’s Nobel speech ['Art, Truth and Politics'], casts an 'unflinching, unswerving' gaze upon the world and shows 'a fierce, intellectual determination … to define the real truth of our lives and our societies'." <P0-S2>  The Prize is shared with an "International Writer of Courage," defined as "someone who has been persecuted for speaking out about [his or her] beliefs," selected by English PEN's Writers at Risk Committee in consultation with the annual Prize winner, and announced during an award ceremony held at the British Library, on or around 10 October, the anniversary of Pinter's birth. <SEP> <P1-S0>  One of the most influential modern British dramatists, his writing career spanned more than 50 years. <P1-S1>  His best-known plays include "The Birthday Party" (1957), "The Homecoming" (1964), and "Betrayal" (1978), each of which he adapted for the screen. <P1-S2>  His screenplay adaptations of others' works include "The Servant" (1963), "The Go-Between" (1971), "The French Lieutenant's Woman" (1981), "The Trial" (1993), and "Sleuth" (2007). <P1-S3>  He also directed or acted in radio, stage, television, and film productions of his own and others' works. <P1-S4> Harold Pinter ( ; 10 October 1930 – 24 December 2008) was a Nobel Prize-winning English playwright, screenwriter, director and actor. <SEP> <P2-S0>  He is best known for his works written in 'synthetic Scots', a literary version of the Scots language that MacDiarmid himself developed. <P2-S1>  However, Grieve's earliest work -- such as "Annals of the Five Senses" was written in English, and from the early 1930s onwards much of the poetry published under MacDiarmid's name was written in an English that was supplemented to varying degrees by scientific and technical vocabularies. <P2-S2> Christopher Murray Grieve (11 August 1892 – 9 September 1978), known by his pen name Hugh MacDiarmid ( ), was a Scottish poet, journalist, essayist and political figure. <SEP> <P3-S0> Professor Duncan Munro Glen (11 January 1933 – 20 September 2008) was a Scottish poet, literary editor and Emeritus Professor of Visual Communication at Nottingham Trent University. <P3-S1>  He became known to the literary world through his first full-length book, "Hugh MacDiarmid and the Scottish Renaissance". <P3-S2>  He published many collections of poetry, from "Kythings and other poems" (1969), "In Appearances" (1971) and "Realities Poems" (1980) to "Selected Poems 1965–1990" (1991), "Selected New Poems 1987–1996" (1998) and "Collected Poems 1965–2005" (2006). <P3-S3>  His "Autobiography of a Poet" was published by Ramsay Head Press in 1986. <P3-S4>  He edited "Akros" magazine through 51 numbers from August 1965 and did much to promote Scottish poets and artists. <P3-S5>  He was a friend and early champion of Hugh MacDiarmid and Ian Hamilton Finlay among others, and produced several volumes of poetry, some of which was translated into Italian.
