Newspaper headlines: Another minister quits over Brexit deal
A grinning Russian President Vladimir Putin is pictured on the front page of the Times as he gives the crown prince of Saudi Arabia an enthusiastic high-five at the G20 summit in Argentina.
The paper says hopes that Mohammed Bin Salman would be given the cold shoulder by world leaders "fell flat" - pointing out that Theresa May and Ivanka Trump both greeted him with a warm handshake.
The Sun believes the prime minister risked a backlash by meeting the Crown Prince.
But the Independent says Mrs May "piled the pressure" on the Saudi leader by demanding transparency in Riyadh's investigation into the killing of the journalist Jamal Khashoggi.
Play it again Sam?
The Business Insider website reports that Sam Gyimah will announce his backing for a referendum following his resignation from the government on Friday night.
It says that while his parting statement hints at support for a fresh vote, he will soon make a public declaration.
The New Statesman's Stephen Bush believes the Mr Gyimah's departure indicates there may be enough support in Parliament to force another referendum.
And Katy Balls from the Spectator agrees, saying that even some Leave-supporting MPs are starting to wonder if a fresh public vote is the only route left to secure a true Brexit now that the prime minister's deal appears even more likely to be voted down.
End of the line
The chairman of the high-speed rail project HS2 and the Crossrail scheme in London is set to be sacked, according to the Financial Times.
Ministers are said to have raised major doubts about the performance of Sir Terry Morgan, with both projects running over budget.
The FT says it is a significant setback for the Transport Secretary Chris Grayling, who only appointed Sir Terry four months ago.
The Guardian says a record number of children are being excluded from school for racist bullying.
Analysis carried out for the paper shows there were more than 4,500 cases last year - up from just over 4,000 in 2016.
The paper outlines three possible reasons: increased bigotry in society at large, a zero-tolerance approach to racism, and a decision made by the coalition government to remove a duty on schools' to monitor incidents of racist bullying.
Campaigners tell the Guardian it is a deeply troubling picture and say the Department of Education should intervene.
Stamp it out
The Daily Telegraph takes a hard line on what it says is a growing online black market for used stamps.
The paper says an uncancelled first class stamp can be bought for 16p on some sites - just a quarter of its face value.
One seller tells the Telegraph they shift about 20,000 every month.
"There's no excuse," thunders the paper's leader column. "It is bad but trivial to reuse stamps at home. But to turn dealer is un-neighbourly - and a crime."
