Theresa May is under pressure after a setback in Brexit talks with Brussels, Saudi Arabia has hinted at retaliation over criticism of the disappearance of journalist Jamal Khashoggi, and the Duke and Duchess of Sussex are kicking off their tour Down Under.
Meanwhile, Gareth Southgate has hit out at the Premier League for not giving players enough rest after the World Cup and Scotland have been beaten 1-3 by Portugal.
If you've been away from a screen or newspaper all weekend or want a summary, here's a quick recap of the main events.
1. Theresa May puts brakes on customs union deal with Brussels
Theresa May refused to endorse a draft Brexit deal negotiated by UK and EU officials on Sunday night amid fears that her Cabinet would fail to back the plan.
British officials led by Ollie Robbins, the Government’s chief negotiator, are understood to have struck an agreement on a detailed proposal which would effectively mean Britain remains part of the EU’s customs union for the foreseeable future. It is the first time a Brexit blueprint had been agreed by both sets of negotiators.
The EU had expected the Prime Minister to be prepared to announce the outline of a deal as soon as Monday and Dominic Raab, the Brexit Secretary, went to Brussels on Sunday for an unscheduled meeting with Michel Barnier.
However, at the 11th hour, Mr Raab set out a series of British concerns over the plan, and all further talks were suspended until Wednesday, when Mrs May will travel to Brussels for a Brexit summit with other EU leaders.
2. Duke and Duchess of Sussex follow in Queen's footsteps Down Under
When the Duke and Duchess of Sussex kick off first Commonwealth tour as a married couple, they will of course follow a careful-curated schedule taking in each of their personal interests.
As they do so, there will be one particular interest never far from their minds: Granny.
The Duke and Duchess, who arrived in a wet and wintery Australia on Monday, are to follow in the footsteps of the Queen and the Duke of Edinburgh throughout their tour, undertaking at least one event which exactly mirrors their visit 65 years ago.
On Saturday, the couple will appear on stage at the Sydney Opera House, where the Duke will deliver a speech welcoming competitors to the Invictus Games.
The night will be particularly poignant for the Duchess. Little over a year ago, in her then-home town of Toronto, Meghan Markle made her first public appearance to watch Prince Harry at work.
3. Saudi Arabia threatens retaliation as criticism mounts
Saudi Arabia has hinted at economic retaliation over mounting international criticism of the disappearance of journalist Jamal Khashoggi as its stock exchange suffered its worst losses in years.
Shares in Saudi Arabia plunged as much as 7 per cent as US President Donald Trump promised "severe punishment", and the foreign ministers of the UK, France and Germany issued a joint statement calling for a "credible investigation" into Mr Khashoggi's fate.
Foreign Secretary Jeremy Hunt and his German and French counterparts said “light must be shed” on Mr Khashoggi’s disappearance, and cautioned that the Saudi government was expected “to provide a complete and detailed response”.
The state-run Saudi Press Agency earlier hit back at the growing chorus of international voices threatening punishment if suspicions that Mr Khashoggi has been murdered are proved true.
4. Duchess of York back in the fold for royal photographs
Weddings traditionally bring families together, and in Sarah, Duchess of York’s case, it finally marked the thawing of royal relations that have been frosty for more than 20 years. The Duchess, once considered an outcast after her toe-sucking antics brought shame on the monarchy in the Nineties, was welcomed back into the royal fold as she posed alongside the Duke of Edinburgh for Princess Eugenie and Jack Brooksbank’s official wedding photographs.
Until Saturday, the 97-year-old Duke and his former daughter-in-law are not believed to have spoken since the Yorks divorced in 1996.
The images, taken by Alex Bramall, a fashion photographer, shows the Duke smiling as the Duchess, who he once described as “odd and pointless”, poses at his side in the White Drawing Room at Windsor Castle.
The photograph, also featuring the Queen, the groom’s family and eight slightly nonplussed bridesmaids and pageboys, was released alongside three others taken at the castle and at the private evening reception at Royal Lodge, the home that the Duke and Duchess of York still share.
5. Merkel's Bavarian allies suffer worst election result since 1950
Angela Merkel’s Bavarian allies became the latest European party to be caught up in the political upheaval sweeping the continent as they suffered historic losses in regional elections on Sunday.
The Christian Social Union (CSU), which has ruled Bavaria for more than 60 years, recorded its worst result since 1950 and will be forced to find a coalition partner if it is to remain in power.
But for once it was not the populist Right that inflicted the heaviest wounds, but the centre-Left in the form of the Green Party which more than doubled its vote.
The results will send shockwaves through Mrs Merkel’s already fragile coalition government, and add to growing calls within her own party for the veteran chancellor to stand down.
6. Southgate hits out at early start to Premier League season
Gareth Southgate has hit out at the Premier League for putting clubs in an “impossible situation” by having to field players without enough rest after the World Cup.
The England manager questioned why the fixtures started on August 10 - just 27 days after his side’s third and fourth place play-off against Belgium and joked that maybe it was because the Premier League were not expecting them to do so well.
Ahead of the Nations League tie away to Spain Southgate suggested the Premier League should do more to help England and English clubs in the Champions League by moving fixtures – as happens around the rest of Europe – and with players suffering from a lack of “psychological freshness” after the exertions in Russia.
“I think it's psychological freshness, rather than physical,” Southgate said when asked why some players had started this season slowly.
7. McLeish feeling heat as Scotland beaten by Portugal
Defeat by what was effectively Portugal’s reserve side – scarcely mitigated by Steven Naismith’s injury-time strike – added to the pressure heaped on Alex McLeish by Scotland’s dismal performance in their Nations League loss to Israel in Haifa three days previously.
The latest wounds were inflicted by Helder Costa, on the verge of half-time, Eder with a powerful header after 73 minutes and Bruma in the closing stages, before Naismith took the sting out of the gathering jeers when he shot home from an inspired backheeled pass from Gary Mackay-Steven.
McLeish, to be fair, also had to reshuffle his pack and had said beforehand that he would have made changes even had he not been obliged, but his hand was certainly forced by the loss of Blackburn’s Charlie Mulgrew, John Souttar of Hearts, along with West Ham midfielder Robert Snodgrass and Scott McTominay of Manchester United.
8. Danny Cipriani presses England claims
Danny Cipriani helped strike a much-needed blow for the credibility of the Premiership in guiding a fretful Gloucester to the first English victory of the weekend in the European Champions Cup.
In the process he further pressed his claims in front of the watching Eddie Jones for a place in the England squad named on Thursday for the Quilter November Tests.
The fly-half crafted and grafted to good effect, popping passes, sliding through kicks, knocking over his goals (14 points) and one late blooper apart, showed up well, much as he has been doing all season.
Victory enhances reputations and, in that regard, the upbeat impact Cipriani has made in his new surroundings has, at least, endeared him to the locals. If only the England head coach were so easily won over.
