Most consecutive weeks in the UK Top 20 (female)

Ruby Murray (UK, 1935-96) had at least one single in the UK Top 20 for 52 consecutive weeks between 3 December 1954 and 25 November 1955. The Belfast-born singer's chart run began with debut single "Heartbeat" and concluded when "I'll Come When You Call" spent its seventh and final week in the Top 20. "Softly, Softly", "Happy Days and Lonely Nights", "Let Me Go Lover", "If Anyone Finds This, I Love You" and "Evermore" also sustained Murray's chart presence during this period. During Murray's chart run, she also set the record for the most simultaneous UK Top 20 singles (female). She achieved five singles on the chart dated 18 March 1955 (at Nos. 2, 5, 14, 15 and 17) and, almost 60 years on, her achievement remains unmatched by a female solo artist on the UK chart. Murray's mark was later equalled by Bill Haley and his Comets in 1956, Elvis Presley in 1957 and Michael Jackson in 2009, and all four acts hold the overall record for the most simultaneous UK Top 20 singles.

Other female contenders include Doris Day (37 consecutive Top 20 weeks with three singles in 1954), Lady Gaga (36 weeks in 2009), Beyoncé (30 weeks in 2008-09), Katy Perry (30 weeks in 2010-11), Rihanna (27 weeks in 2012-13), Jessie J (25 weeks in 2011) and Adele (19 weeks in 2011). Kimbra achieved 26 consecutive weeks as featured vocalist on Gotye's 2012 chart-topper "Somebody that I Used to Know". Judy Collins' "Amazing Grace" (released in 1970), which at 67 weeks remains the UK single by a solo female with the most cumulative weeks on the chart, managed just 13 successive weeks in the Top 20, in 1971.

Murray's 52-week stay on the UK chart featured seven of her 10 UK hits. "You Are My First Love" (No.16 in 1956), "Real Love" (No.18 in 1958) and "Goodbye Jimmy, Goodbye" (No.10 in 1959) complete the singer's list of UK hit singles.

Murray released six singles between January and October 1955 alone, including her only No.1, "Softly, Softly".

When "Softly, Softly" reached No.1 on 18 February 1955, Murray (b. 29 March 1955) became the youngest singer to top the UK singles chart, aged 19 years 10 months 20 days. At that time, the UK chart was just two years and three months old (Al Martino's "Here in My Heart" was the UK's first No.1 record, on 14 November 1952).

In 1954-55, the UK chart was officially a Top 20. Nowadays, the Top 75 is regarded as the official portion of the chart.

Murray died of liver cancer on 17 December 1996, aged 61.
