Pop group Abba will never reform, one of the Swedish band's songwriters and former members has said.

Bjorn Ulvaeus said the band would not follow other acts by regrouping, as their "creativity" together had gone.
He said: "We felt that the energy was running out towards the end of the 1970s. We decided, why should we do a Rolling Stones or a Queen?"
Abba were one of the most successful pop groups of that decade, with hits such as Waterloo and Dancing Queen.
Ulvaeus and songwriting partner Benny Andersson wrote the band's songs, selling more than 100m albums worldwide.
He said: "We believe that what we did then was pretty good.
"Abba was the highlight of mine and Benny's creativity, and most groups actually only have seven or 10 years of creativity.

"Some of them go on anyway."
Ulvaeus said he considered Madonna's recent sampling of Abba hit Gimme Gimme Gimme on her UK number one single Hung Up to be "a tribute".
He said: "We have loads of offers like that but we never say yes, but in this case it was so cleverly done."
The Abba songwriting partners are attempting to transfer their Swedish musical Kristina, about a group of immigrants, to Broadway.
Abba's songs became the basis for the hit musical Mamma Mia!
In February, the four original members - Ulvaeus, Andersson, Agnetha Faltskog and Anni-Frid Lyngstad - met publicly for the first time in more than 20 years at the musical's Stockholm premiere.
