Paris St Germain celebrated their first Ligue 1 title in 19 years following a 1-0 win at Lyon.
Jeremy Menez's 53rd-minute strike was enough to end the capital club's long wait to reclaim the French crown and seal a first title since their big-spending Qatari owners took charge.
PSG's title will not, however, be confirmed until a league disciplinary panel meets to decide whether to impose a points deduction following allegations sporting director Leonardo barged a referee.
The Brazilian will front a hearing before the end of the season after he was charged for an incident that took place in the tunnel after PSG's 1-1 draw with Valenciennes at the Parc des Princes last weekend.
Reports have suggested PSG could be handed a two-point ban, with the club now seven points clear of nearest-rivals Marseille with two games to play.
Marseille had ensured PSG's title party would have to wait until Sunday at least with a 2-1 victory over Toulouse at the Stade Velodrome 24 hours earlier.
An Andre Ayew brace either side of the break was enough to see off 10th-placed Toulouse and guarantee Champions League football for the hosts next season.
Despite a late Eden Ben Basat goal, an eighth away defeat of the season for Alain Casanova's men all but guaranteed a mid-table finish.
St Etienne's European hopes suffered a blow as they lost 3-1 at Lorient.
After dominating the first half, the hosts went ahead five minutes after the break through Kevin Monnet-Paquet.
Fabien Robert doubled the lead in the 67th minute and, although Kurt Zouma pulled one back 11 minutes from the end, Yann Jouffre made the points safe in injury time to leave St Etienne needing favours from others on the final day of the season to qualify for the Europa League.
At the other end of the table, Troyes continued their gutsy last-ditch bid for survival with a 1-0 win at Ajaccio.
Jean Marc Furlan's men climbed off the bottom of the standings last weekend by beating Evian and they are now just a point from safety thanks to Florian Jarjat's first-half strike in Corsica.
Evian gave their survival hopes a much-needed boost with a shock 4-0 hammering of Nice at the Parc des Sports.
Saber Khelifa scored twice as the hosts emulated the scoreline by which they beat Lorient on Wednesday to reach the Coupe de France final.
This latest success, which also featured goals from Kevin Berigaud and Mohammed Rabiu, lifted Evian two points ahead of Nancy and out of the relegation zone with two games remaining.
Cheick Diabate struck a late winner as Bordeaux increased Nancy's relegation fears at the Stade Jacques Chaban-Delmas with a 3-2 win.
Nancy had looked on course for a miraculous escape from the drop after picking up 17 points from a possible 24 recently, having previously won just twice in 25 league matches, but they lost 3-0 at home to Lyon last week and suffered more disappointment on Saturday night.
Nancy appeared to have snatched a point when second-half goals from Loosemy Karaboue and Salif Sane cancelled out two Bordeaux goals in the final five minutes of the first half from Andre Biyogo Poko and Henri Saivet.
But there was a late twist in the tale as Diabate popped up four minutes from time to earn Bordeaux the victory.
Bastia guaranteed survival as Anthony Modeste scored two and set up the other to see off Montpellier 3-1.
Modeste scored twice to secure the win after John Utaka had cancelled out Claudio Beauvue's opener for the hosts.
Two goals from Sloan Privat moved Sochaux to the brink of safety, while condemning hosts Brest to a 2-0 defeat which leaves them on the brink of relegation to Ligue 2.
Privat's second-half double subjected Brest to an eighth successive defeat which means Landry Chauvin's team are six points from safety with just two games remaining.
Nine-man Rennes experienced second-half misery at Stade du Hainaut as they fell to a 4-1 defeat against mid-table rivals Valenciennes.
Things began well for the visitors when Jonathan Pitroipa fired them in front on the half-hour mark before Maor Melikson levelled the scores soon after.
But the evening quickly went downhill after the interval as first Dimitri Foulquier and then John Boye were sent off within the space of six minutes.
With their obvious advantage, Valenciennes took control and goals from Lindsay Rose, Kenny Lala and Jose Saez wrapped up an emphatic win which moves the club above their opponents on goal difference.
Salomon Kalou scored twice as Lille moved into a Europa League spot with an emphatic 3-0 win over Reims on Friday night.
Kalou struck in either half, sandwiching a strike by Dimitri Payet as the hosts moved into fourth spot ahead of Nice on goal difference, with Claude Puel's side playing Evian on Sunday.
Defeat leaves Reims five points above Evian, who occupy the third relegation spot with the latter having three games remaining.
