Bosh! Less than 0.1s between Nico Rosberg and Lewis Hamilton as the latter goes round in 1:22.997, enough to sneak him ahead of his Mercedes team-mate, though.

"Water leak for Kimi - end of session and the car's going up on jacks."

A 1:23.095 for Nico Rosberg and he moves 1.3 seconds clear at the top of the standings. Lewis Hamilton heads out for his first run on the softs now. Time to see what the championship leader can do.

Nico Rosberg re-emerges with softs strapped on his Mercedes and embarks on his first flyer on the compound. All looking good with his lap so far...

Some bad news for Kimi Raikkonen as Jennie Gow reports from the Ferrari garage that his car has a "major water leak". He remains in his seat, so is perhaps hopeful of getting back out at some point in the final 15 minutes.

Meanwhile, it is all relatively quiet on the circuit with just the two Force Indias and the Red Bull of Daniil Kvyat circulating the track.

"There is very little happening on Lewis Hamilton's side of the garage - no changes to the car since that last run but on Nico Rosberg's car a lot of changes - both front and rear suspension changes. He was not happy with the balance of his Mercedes on Friday, particularly over one lap."

Lotus: While Romain & Pastor are doing longer runs, Julien & Mark sneak in a quick game of battleship.

Lewis Hamilton, by the way, has the second fastest time at the moment with 1:24.747, two tenths slower than Nico Hulkenberg's timesheet-topping effort on the softs.

Hulkenberg, Sergio Perez and Fernando Alonso are the only drivers to have taken on on softs so far this morning, but their rivals are heading into the pits now with just over 20 minutes left.

Turn One is causing one or two drivers a bit of bother as Nico Rosberg locks up there, as does Lewis Hamilton, prompting white smoke to pour off the front right tyre.

Nico Hulkenberg's first run on the softs sees him up into P1 with a 1:24.483 while Sergio Perez is just over nine tenths of second slower with 1:25.393.

Nico Rosberg's first timed lap - a 1:24.873 - sees him storm to the top of the timesheet while Red Bull finally join the party and Daniel Ricciardo gets up and running with a 1:25.697.

Meanwhile, the Force Indias are bolting on the softs and about to head back out on to the circuit....

Kimi Raikkonen circulates in 1:25.661 to move top of the pile, two tenths faster than his Ferrari team-mate Sebastian Vettel.

Just over 20 minutes in and we are just waiting for Mercedes and Williams to set times, while Red Bull are still to emerge from the garage.

"A bit like Red Bull, McLaren were expecting Hungary to be their best chance for a decent showing for a while, even if their problems with the Honda are somewhat more severe than those of Red Bull with Renault - not that you would know it from the way the two teams are managing their public relations. Fernando Alonso and Jenson Button were duly eighth and 11th in second practice, and both professed themselves to be enjoying the car. Button has targeted a place in the top 10 shoot-out but Alonso is not convinced that is realistic.

"'We saw that on Fridays some people are not showing their potential, like Williams,' Alonso said. 'They run quite heavy or quite slow and then on Saturday and Sunday they are very competitive. Force India didn't run in FP2 so potentially there are some cars that will be in front of us. But I am happy with the performance of the car - a little bit better at every race, trouble-free Friday for us, so positive start but the important thing is in qualifying and especially the race.'"

Grip was a problem for a few drivers yesterday and it is giving Jenson Button a bit of a headache in the early stages of this session.

"Very, Very , very poor rear grip. We've lost all rear grip - traction," says the McLaren driver over team radio.

Sergio Perez loses the rear of his Force India at the apex and spins, prompting a brief appearance of the yellow flags. He recovers without fuss and gets back on his way.
