Former Abba member Bjorn Ulvaeus joined BBC Breakfast to talk about his latest musical projects and why Abba will never perform again.

This year marks the 40th anniversary of Abba winning the Eurovision song contest with Waterloo.

Following their win, they went on to sell nearly 400 million singles and became one of the biggest bands in the world.

However, despite their success Bjorn says they will never perform again as a band.
