Elon Musk and Twitter Inc agreed to postpone the billionaire's deposition scheduled for today as they try to reach an agreement to end their litigation and close Mr Musk's €44.3bn purchase of the social media company, a source familiar with the litigation said.

No new time has been set.

Mr Musk and Twitter are currently attempting to reach an agreement after months of litigation that damaged Twitter's brand and fed Mr Musk's reputation for erratic behaviour.

Meanwhile, Apollo Global Management Inc and Sixth Street Partners, which were looking to provide financing to Mr Musk, are no longer in talks with the billionaire entrepreneur, according to two sources familiar with the matter.

Earlier this year, Apollo was in talks to provide preferred equity financing for the deal, alongside Sixth Street, sources had previously told Reuters.

Apollo, Sixth Street and other investors were looking to commit over €1bn in financing for the deal at the time.

Those talks ended months ago around the time Mr Musk started having second thoughts about going through with the deal, the sources said.

Mr Musk initially proposed the buyout in April, before backtracking in July, and then changing course again this week.

Twitter and Mr Musk did not immediately respond to request for comment, while Apollo and Sixth Street declined to comment.

Mr Musk is expected to provide much of the €44.3bn through funds he has raised by selling down his stake in electric vehicle maker Tesla Inc and by leaning on equity financing from large investors, while major banks have committed to provide close to €13bn of debt financing.
