Lewis Hamilton is back in the Mercedes garage and out of his car. He was told to box after Mercedes lost all telemetry and it is a frustrating day so far for the world champion. He certainly doesn't look best pleased as he stands around in the garage.

BBC Radio 5 live analyst"Daniel Ricciardo needs to do a bit of attacking because he is only seventh fastest at the moment. He is behind the sister car, the Toro Rosso, of Max Verstappen. He is also 1.6 seconds off Nico Rosberg, a heck of a long way."

Image source, Getty ImagesMuch like in the build up to the Australian GP - when the bizarre legal battle between former F1 driver Giedo van der Garde and Sauber dominated the headlines - there has been some soap opera style shenanigans in the lead up to this race.
A once happy marriage between Red Bull and engine partner Renault - who together won world titles between 2010 and 2013 - looks to be on the rocks after a bit of verbal sparring between the two.
After Red Bull's technical guru Adrian Newey claimed there was "no obvious light at the end of tunnel", external with the Renault engine, saying "it is quite a long way behind" its competitors, Renault's engine chief Cyril Abitebou responded with "it is hard to have a partner who lies".
Is this a relationship that is destined to end in a messy divorce?
