A Red Wall Tory minister aged just 29 has announced she will not stand at the next election - becoming the fourth Conservative in a week to do so.
With the ruling party facing wipeout the next time the country goes to the polls, levelling-up minister Dehenna Davison has announced she is stepping down.
In a statement she said she hasn't "had anything like a normal life for a 20-something".
She joins a string of MPs who have announced their time in Parliament is over, including former Work and Pensions Secretary Chloe Smith, who was once among the youngest MPs in Parliament.
Thirty-something 1922 Committee vice-chairman William Wragg is also standing down as is the Tory MP Gary Streeter. Veteran Conservative backbencher Charles Walker has also previously said he will be standing down.
Tory MPs have until December 5 to announce whether they will stand again, with party chiefs fearful of an exodus.
Earlier this week Ms Davison, who was elected in Bishop Auckland in 2019, sparked bafflement when she skipped a conference in Manchester an accidentally sent the wrong video.
Today she said: "For my whole adult life, I've dedicated the vast majority of my time to politics, and to help make people's lives better.
"But, to be frank, it has meant I haven't had anything like a normal life for a 20-something.
"I will always be humbled to have had the opportunity to serve as a Member of Parliament. But now the time feels right for me to devote more of my attention to life outside politics, mainly to my family and helping support them as they've helped support me.
"That's why I won't be standing in the next general election."
In 2019 she secured a majority of 7,962 as the Tories took the seat from Labour, but the County Durham constituency is likely to be a key battleground next time around.
Ms Davison said she became interested in politics after her father was killed when she was 13 by a single punch.
She has campaigned for better support for families affected by families such as hers.
The MP previously worked as a parliamentary aide for former cabinet member Jacob Rees-Mogg.
She also appeared on a Channel 4 documentary, Bride and Prejudice, after marrying Conservative councillor John Fareham, 35 years her senior.
Brought into government by Liz Truss, Ms Davison was kept on in the role under Rishi Sunak when he took over as Prime Minister and her prospects in the party had seemed high.
Her decision to quit will further spook party leaders as the Tories lag behind Labour in the polls.
