Abba's Gold compilation has not topped the UK album chart since 1999
Abba's greatest hits compilation Gold, first released in 1992, has become the oldest album to top the UK album chart.
The record, which has made it to the top spot on four previous occasions, knocked Coldplay's Viva La Vida Or Death And All His Friends down to two.
In the singles chart, US musician Kid Rock has ended rapper Dizzee Rascal's four-week reign with his track All Summer Long - last week's number two.
Ireland's The Script climb 27 places to three with The Man Who Can't Be Moved.
That rise, however, is dwarfed by American singer Katy Perry's controversial track I Kissed a Girl, which has jumped 135 places to become this week's number four.
Swedish supergroup Abba are enjoying a new surge of popularity at present thanks to the release of Mamma Mia! in cinemas.
The film's soundtrack of exuberant Abba covers reached the top spot itself last month.
With sales in excess of 26 million copies, Gold is the fourth biggest-selling album of all time in the UK.
The record originally reached number one in 1992, repeating that feat three times in 1999.
