Noel and Liam Gallagher reconcile just in time for the 30th Anniversary of "Definitely Maybe".

Almost 15 years to the day after Noel Gallagher pulled the plug on Oasis in 2009, issuing a statement declaring "I simply could not go on working with Liam a day longer," the brothers Gallagher announced that a new day is dawning: Oasis plans to reunite in 2025 for a tour that would coincide with the thirtieth anniversary of their blockbuster (What's the Story) Morning Glory.

Who else is in the band?

Oasis were formed in Manchester in 1991 - their original line-up comprised of Liam and Noel, guitarist Paul "Bonehead" Arthurs, bassist Paul "Guigsy" McGuigan and drummer Tony McCarroll.

But the line-up changed over the years (scroll down for more detail), before their last performance at V Festival in 2009.

Bonehead and Liam have remained friends, and the guitarist has joined Liam at some of his shows.

Currently, it isn't entirely clear exactly who fans will be seeing perform on tour, beyond the Gallagher brothers. BBC News has asked the promoter for clarification.

Why did they break up?

The band officially split in 2009 after an altercation backstage at the Rock en Seine festival in Paris.

Noel explained two years later that during an argument, Liam had tried to attack him with his guitar.

He claimed the row had started after he blocked Liam from advertising his clothing brand in the programme for V Festival, at which the pair were due to perform.

Liam said in 2017 he had felt unfairly scapegoated by Noel and left to shoulder the blame for the band's split.

But problems had been brewing before the festival incident - with the pair struggling to agree on the artistic direction of Dig Out Your Soul - their final album - which was released in 2008.

Many fans will be intrigued to see how relations between the brothers will play out 15 years on from their split.

How has the Oasis line-up changed over the years?

The group began with five members when they formed in 1991.

This included Paul Arthurs on guitar, Paul McGuigan on bass guitar and Tony McCarroll on drums - with Liam Gallagher on lead vocals and Noel on lead guitar and vocals.

McCarroll was replaced by Alan White in 1995 and Arthurs and McGuigan were replaced by Gem Archer and Andy Bell in 1999.

White then left the band in 2004 and was replaced by Zac Starkey and then he gave way to Chris Sharrock in 2008.

The remaining members of the band continued with Liam Gallagher and formed the new band Beady Eye, which disbanded in 2014.

It's not known who, if any, of the former band members will join Liam and Noel on tour next year.

Why are they doing this now?

A statement from the band said: "The guns have fallen silent. The stars have aligned. The great wait is over. Come see. It will not be televised."

Only those who were in the room with Noel and Liam - aged 57 and 51 respectively - when they decided to reunite will know the real reason for their reconciliation.

Many wrote them off, saying it was implausible that they'd ever play together again - especially after Noel declined to appear on stage with Liam at One Love Manchester after the city was rocked by the Ariana Grande concert bombing.

The cynical answer is of course that 17 huge shows (so far) will generate a lot of income for the band.

If Taylor Swift's Eras Tour is anything to go by, they could rake in around £14m per concert.
