While Slater has dominated Ginetta Junior this season, Clarke has been the undisputed star of the Clubmans Sports Prototype category and scored another two triumphs in his Phantom PR22 at Oulton Park, his lead almost 40 seconds each time.
Not only do those successes narrow the gap to Slater, but they also propel Clarke back to second a week after dropping behind Lucas Romanek.
It was a rare weekend without Romanek being in Formula Ford 1600 action and McLeish relegated him another place as he also picked up two wins.
Having enjoyed plenty of glory in the Scottish Legends series, McLeish entered his local round of the British Touring Car-supporting Elite Cup contest at Knockhill and continued his strong form. He also moves up one spot on the leaderboard.
Behind Romanek, in fifth place is another driver to move up one place as Aidan Hills achieved a Mazda MX-5 Supercup win at Cadwell Park. But it was just the one victory this time for Hills, who was narrowly defeated in the opener.
Another MX-5 conqueror was Steve Foden, who twice topped the Mk1 championship to jump two places into sixth.
Other regular frontrunners to add to their totals last weekend include Junior Saloons pacesetter Daire Flock (two wins at Croft send him from 15th to ninth) and BTCC title contender Jake Hill (up from 27th to 13th).
One driver to provisionally seal a championship was Classic Stock Hatch star Stewart Place, after netting another three wins in his Peugeot 205 at Snetterton. The hat trick means he also climbs 27 places to 15th.
Further improvers inside the top 20 are Dan Silvester (a Snetterton Hot Hatch success sends him from 23rd to 17th) and Ash Sutton's Knockhill BTCC win moves him from 25th to 20th.
Two places further back is Mini Challenge master Dan Zelos, who won twice in Scotland and is now the most successful driver in terms of wins in series history. He also jumps up 17 spots in the rankings.

All car races in UK and Ireland are included except qualification/repechage, consolation and handicap races. No races in other countries.
Class wins are only counted when there are at least six starters in the class. Only classes divided by car characteristics are included. Classes divided by driver characteristics such as ability, professional status, age, and experience (for example rookie or Pro-Am classes) are not included. Each race counts only once, so an overall winner’s class win is not added.
Where there is a tie, overall wins take precedence. Where there is still a tie, the average grid size for a driver’s wins determines the order.
