Watch: ITV announces it's bringing back Big Brother

Big Brother is preparing to return to British TV screens after a five-year hiatus.

The reality show, which aired for 18 years before being axed in 2018, has been picked up by ITV for a new series.

Here is everything we know so far about the reboot.

When is Big Brother returning?

The Big Brother house will reopen its doors in 2023 with a new series aimed at younger viewers.

The basic premise will remain the same: housemates living together for up to six weeks, with their every move filmed by surveillance cameras.

But the famous house will feature a "contemporary new look" and a batch of contestants from "all walks of life".

The revival will be shown on ITV2 and new streaming platform ITVX. The broadcaster has yet to reveal an official launch date.

ITV2 controller Paul Mortimer said the series would "contain all the familiar format points" from the original show, including live evictions and cash prize for the winner.

But he teased "some additional twists that speak to today's audience".

He said: "We're beyond excited to bring this iconic series to ITV2 and ITVX where it should especially engage with our younger viewers."

Why was Big Brother cancelled?

Big Brother initially ran on Channel 4 between 2000 and 2010, helping to launch the careers of Jade Goody, Alison Hammond and Adele Roberts.

The reality series moved to Channel 5 in 2011 but was cancelled in 2018 as ratings slumped.

Big Brother's production company said at the time that there were "future possibilities" for more series on UK TV, prompting speculation it could be revived.

Channel 5 controller Ben Frow later said he had no regrets about ending the series, adding: "The world is very crowded with reality shows."

Who will present the new series?

Davina McCall hosted Big Brother during its stint on Channel 4, but was replaced by Brian Dowling and Emma Willis for its run on Channel 5.

The reboot is likely to bring in a new presenter, however, as ITV seeks to attract a new audience.

Rylan Clark, who won Celebrity Big Brother in 2013, has previously said he would take the job "in a heartbeat".

Writing on Twitter after the show's return was confirmed, the Ready Steady Cook presenter said: "Should clarify, I've not been asked to host the show.

"As a fan, like always, I'm made up it's coming back. I know how hard we all fought to keep that name alive and I'm so glad it paid off."

Jedward, who appeared on the celebrity version of the show in 2011 and 2017, have offered to host the show, calling themselves "iconic housemates".

Meanwhile, Big Brother narrator Marcus Bentley has said he is "quietly confident" he will return for the 2023 series.

He told RadioTimes.com: "I'm not confirmed. It's very early days. I think it sounds like I am.

"I'm getting calls from [producers] and they're going to keep me updated. But they haven't chosen anything."

Is Celebrity Big Brother coming back?

It is not clear if Celebrity Big Brother will also return.

The most recent celebrity series was won by former Coronation Street star Ryan Thomas in 2018.
