Jenrick was dismissed from the Conservative Party for planning to defect to Reform UK, which he subsequently joined.
A new poll indicates that half of Britons support Ms Badenoch's decisive action, with 45 per cent of Reform voters also approving of her handling of the defection.
The public views Jenrick's sacking as reflecting well on Ms Badenoch (34 per cent) but poorly on Jenrick himself (37 per cent).
The survey also suggests a 'cost of defections', with 70 per cent of Conservative voters stating they would not support an MP who switched to Reform UK.
