Along with this decision, he is also stepping down as schools minister as part of a recent cabinet reshuffle.
In his resignation letter, Gibb expressed concern about the growing cynicism and hostility towards politicians, which he believes is hindering the ability to solve problems collaboratively. He also mentioned his new role in diplomacy but did not provide specific details.
Gibb, who has been an advocate for phonics in education, highlighted the progress made in this area during his tenure as schools minister. He claimed that, partly due to these efforts, England's children are now among the most accomplished readers in the world.
In a personal reflection, Gibb, who publicly came out as gay in 2015 and married his long-term partner, acknowledged the support and love he received from his husband, describing him as "brilliant, principled, and adorable."
Gibb's departure marks the end of a significant chapter in his political career, where he has been a familiar face in education policy.
