Washington Post journalists have begged the newspaper's billionaire owner Jeff Bezos to spare their jobs - while his wife Lauren Sanchez flaunted expensive couture outfits at Paris Fashion Week.

Up to 300 Post staffers are set to be affected by job cuts as CEO Will Lewis transforms the paper and reverse millons of dollars in losses each year, Puck reported.

The hashtag #SavethePost gained traction among the Post's current and former journalists this week as a result. 

It comes as Bezos joined his wife at the Christian Dior Haute Couture show in Paris on Monday. Sanchez cut a stylish figure in a pale blue skirt and matching jacket, complete with a lavish fur collar.

Back in the United States, furious Post employees were demanding Bezos ditch plans for cuts.

In a statement, the Washington Post Guild wrote: 'The Post Guild vehemently opposes any more cuts to the staff of The Washington Post.

'As we've seen in recent years, continuing to eliminate scores of workers who make this storied institution what it is only stands to weaken the newspaper, drive away readers and undercut The Post's mission: to hold power to account without fear or favor and provide critical insight into communities across the region, country and world.

'If Jeff Bezos no longer supports that mission, then The Post and its readers deserve a steward who does.'

CEO Will Lewis has reportedly decided to focus the paper on 'core coverage areas' like national security and politics. The sports desk is expected to bear the brunt of the costs, according to Puck.  

Individual staffers responded to news of the cuts, including Mexico bureau chief Samantha Schmidt.

Schmidt wrote: 'As international correspondents and reporters for the @washingtonpost, we risk our safety to investigate authoritarian governments, report from gang-controlled towns and document evidence of stolen elections. 

'This on-the-ground reporting is more critical than ever.' 

Ukrainian bureau boss Siobhan O'Grady tagged Bezos in her post, which thanked the mogul for his 'support for our essential work documenting the war in Ukraine, which still rages.
