Conservative MP Dehenna Davison has resigned as a levelling up minister, saying “chronic migraines” have made it “impossible” to do her job.
Writing to the prime minister, the Tory MP said people deserved “a minister who can give the job the energy it needs”.
She said serving in government had been “an immense privilege that I will forever remember”.
She also pledged her “wholehearted support” to Rishi Sunak’s government from the backbenches.
Ms Davison became an MP in the 2019 general election taking the traditional Labour stronghold of Bishop Auckland in County Durham.
However just three years into her parliamentary career she announced that she would be stepping down at the next election, saying she wanted to devote more time to “life outside politics – mainly to my family”.
Ms Davison said her health problems had had a “great impact” on her ability to carry out her government role.
In her resignation letter, Ms Davison said: “I write to ask to leave my role as Levelling Up Minister and to step back fully from Government.
“Unfortunately for some time now I have been battling with chronic migraine, which has had a great impact on my ability to carry out the role.
“Some days I’m fine, but on others it is difficult, if not impossible to keep up with the demands of ministerial life – and the timing of such days is never predictable.”
She added: “At such a critical time for levelling up, I believe the people of communities like mine, and across the country, deserve a minister who can give the job the energy it needs.”
Responding to her resignation, Levelling Up Secretary Michael Gove said: “Really sorry to lose Dehenna from the department – a brilliant minister and kind friend. Wishing her all the very best for the future. She has so much to offer.”
Conservative MP Jacob Young has been appointed to replace Ms Davison as a minister in the Department for Levelling Up, Housing and Communities.
