And he has got a fight on his hands! 𝕴Toprak Ra𒁃zgatlioglu takes P1 away with a minute to go.

2mins to go and Bulega hits the top! 0.163s quicker than Iannone. The Aruba ꦜrider is fighting to keep his perfect sweep of t🌜he four test sessions.

Bulega goes third, just 0.1s from the top. 

But Iannone does even 🍨better and goes fa๊stest with a 1m 29.797s.

Bautista split♔s the Lowes brothers in 2ꦛnd, with team-mate Bulega up to 10th.

5mins to go and 🗹test leader Nicolo Bulega finally heads out.

15mins to go.

Marc VDS rider Sam 💃Lowes makes it a British one-two by replacing Nagashimaไ in second.

Redding improves again, to a🗹 1m 30.9s and is now two-seconds clear. 

Redding slices time off in all four sectors and sets a 1m 31.1s, which is only 1.2🙈s off his fastest lap of the test.

Those lap times look to have prompted others to head out, including re🍸turning Ducati rider Scott Redding.

Redding  blasts straight to the top with a 1m 32.1s, 3sec clear of Montella, and is going even quicker o💦n his next lap.

The track continues to dry and Montella suddenly breaks into the 1m 38s on sl🥃icks. Nagashima is hot on his heels.

The crossover point between wets and slicks will be valuable ꦡinformation if - or when - rain arrives during the race weekend.

Razgatlioglu's team-mate Michael van der 🍌Mark also does a slow lap🐼 and then pits.

The Barni rider shows he's still formidable in the we𓃲t by 🤡going quickest on only his second lap. Presumably happy, he then pits.

🔯Vickers pits 🅰and Danilo Petrucci heads out. The Italian is a MotoGP winner in the wet so let's see what he can do.
