Celebrity Big Brother 2018 lineup: Rachel Johnson - sister of Boris - announced as first housemate in all-female series

The Channel 5 series will celebrate 100 years since women first voted

Rachel Johnson, the only contestant confirmed for this year's Celebrity Big Brother

The first Celebrity Big Brother 2018 housemate has been revealed.

Journalist Rachel Johnson - sister of politician Boris - is the first person confirmed to be entering the all-female house when its doors open on 2 January.

The 52-year-old was officially announced a part of next year's line-up by the Channel 5 reality series' official Twitter account. Johnson, who has worked for Financial Times, the BBC and Mail on Sunday, was the editor of The Lady from 2009 to 2012.

Commenting on her decision to enter the house, Johnson wrote in her Mail on Sunday column: “I’ve never sat down and watched CBB in the way my children religiously binge-watch it, but when Channel 5 came calling, I didn’t delete the annual email asking me to be on. It was because this one said that the new series was all about female empowerment and 100 years since women got the vote.

“It was going to be called Big Sister (it’s ended up being called Celebrity Big Brother: Year Of The Woman), with a “classy” all-female line-up for the launch. Female politicians, performance artists, broadcasters. Serious stuff. Big names were duly dropped, and the emphasis on “empowerment” rather than “ritual humiliation” promised.”

She added: “I am a firm believer that you only regret the things in life you don’t do, not the things you do do.”

Her father, former Conservative MP Stanley Johnson, recently appeared on ITV reality competition I'm A Celebrity... Get Me Out of Here which was won by Georgia Toffolo.

Celebrity Big Brother: Year of the Woman - hosted by Emma Willis - begins 2 January 2018 on Channel 5.
