Host Jack Whitehall had a sit-down chat with McLaren's Lando Norris earlier, who says he is "working hard" before the season gets under way in a month's time.

On what he got up to in the winter break, he said: "I made the most of it, everyone deserves a good off-season so I spent some time with my family and my friends, and a bit of Netflix and chill."

Max Verstappen is here. He hasn’t pulled a sickie.

The four-time world champion is aiming to become only the second driver since seven-time winner Michael Schumacher during his Ferrari domination of the early 2000s, to win five consecutive drivers’ titles.

With the early predictions suggesting the field could be as close as ever, does the Red Bull man think 2025 could be a season for the ages? “I mean, it would be nice,” said

“You can speculate about it, but it’s just a waste of energy to think about that yet. I mean. I hope so, it’s good for the sport.”

Rookie Liam Lawson, meanwhile, who replaced Sergio Perez in the team, says the chance of a seat at Red Bull is a “big opportunity” for him. “I’m excited for my first proper season and I’m just ready to go now,” the New Zealander added.

Here comes F1 reigning champion Max Verstappen's team Red Bull!

Boss Christian Horner walks onto the stage, met with boos from the crowd.

"Of course you're here" Jack Whitehall tells Gordon Ramsay. He's always in the paddock, loves a bit of F1 he does!

"Let them be real, let it go!" Ramsay says in response to the swearing ban. He also says a naughty word. I don't think the bosses will like that.

The 2025 Mercedes is shown to the O2 Arena. Does it look any different to last year’s livery? Nope.

There is plenty of adoration for George Russell as he’s described as the team’s new leader. Andrea Kimi Antonelli, who was only two days old when Fernando Alonso came second at the 2006 Turkish Grand Prix, is also lavished with cheers.

“Scottish Mary Berry” Gordon Ramsey, as Jack Whitehall teases him, is here tonight. He’s asked about the swearing ban, and then promptly drops the S bomb. Pound in the swear jar.

George Russell brings the jokes to the stage during Mercedes' reveal, saying: "I've got my sister in the audience but she's only come here to see Jack Whitehall, so I'm not sure how I feel about that to be honest."

There's a cheer before George Russell talks. The new team leader, he's called.

He has big Lewis Hamilton-shaped shoes to fill!

Boss Toto Wolff walks out with drivers George Russell and Andrea Kimi Antonelli.

George waves to the crowd as they strut down the walk.

"Such an amazing event," Wolff says.

Before Mercedes took their turn in front of the media, Andrea Kimi Antonelli was brought round the media centre and introduced to various journalists. I was sat just in front of the Italian contingent, who were enthusiastically congratulating the 18-year-old on his upcoming Formula 1 debut.

Antonelli, who has been a Silver Arrows’ protege since the age of 11, was keen to point out he is “not a replacement” for seven-time world champion Lewis Hamilton. “I’m just the next Mercedes driver,” he said. “I want to make my own story; try to make the best of these opportunities.”

George Russell, meanwhile, is starting his fourth season with the team (seventh year in F1) and he reflected that last year - he finished sixth in the championship and won two races - was his “strongest” campaign so far.

Russell, who celebrated his 27th birthday last week, gave an indicator as to how the drivers can tell during the opening race if the pre-season work has paid off for a team. “Within five laps you know if you’re in for a good season or not,” he said.
