@Mcf1: Well, his contract runs until the end of this season, but Ron Dennis always said it was a watertight deal without any clauses in it. We'll see - he might well be reading the smallprint right about now.
Quite a few teams taking advantage of the extension - Hamilton, Verstappen, Magnussen out there, as are Giovinazzi and Palmer, who have two laps between them so far today.
@DiogoAnchieta: They have an engine? News to me.
Hamilton is out on the ultra-softs. Brace for a quick lap time.
Unspectacular sectors from Hamilton so far however.
@krishna: I could, but that would literally take up all of my time and I would rather answer questions and give a general overview of what's going on!
@Siddhesh: Good question. Maybe Liberty will make things easier for the fans to follow these events in future, who knows.
The chequered flag has dropped on the session, that's all she wrote for the morning. Palmer got himself a solitary installation lap in, but only Magnussen imroved on his previous lap times.
Times to be updated imminently.
@MB99999: I reckon he hit traffic or didn't get a good warm up lap on them, as he had all yellow sectors and returned to the pits. It might well have just been a cursory lap on them to get a general feel while they had a throwaway five minutes at the end of the session.
That's lunch for us here at the Circuit de Catalunya - though doubt it will actually be lunch for me as I'm dashing down to Haas to speak to Magnussen about his second day in the car so far. Updates to follow later this afternoon.
Lunchtime is over and we are green for the afternoon session at the Circuit de Catalunya.
During the lunch hour, Williams has confirmed it has been forced to cut-short its running for the day following F1 rookie Lance Stroll's spin earlier in the morning.
A brief red flag before the Sauber of Giovinazzi is able to complete his outlap. However, the circuit quickly returns to green with the Italian managing to get his car back to the pit lane under his own steam.
@Vinay: No confirmation from Renault as to why Palmer did not set a lap time before lunch. He is, however, on track now and setting about completing his first timed runs.
Palmer does finally get a time on the board, recording a 1:27.712s to go ninth.
@siddish Thank you! They have indeed both headed to the paddock, so I'm afraid you will have to put up with me for the time being until they get back!
Palmer continues to improve with every lap he sets. He remains ninth but moves to within 0.6s of Vandoorne.
Bottas is the latest man to hit the track, having taken over from Mercedes teammate Hamilton who ran this morning. Hamilton completed 66-laps this morning, which is exactly the race distance of the Spanish Grand Prix.
The Finn has gone straight out on the soft tyre. It will be interesting to see if he follows the same run plan as his teammate did this morning by getting a go on the super-soft compound later on.
Bottas' first lap puts him eighth. He is over five seconds slower than Hamilton's best time at this stage.
Bottas has moved himself up to seventh with a further improvement, displacing his former team in the process as Stroll (who is not running this afternoon) drops to eighth.
@TxTodd No Shark Fin on the Merc today as yet. It is once again running a T-Wing, this time with a second tier.
Raikkonen joins the action in his Ferrari.
