His promotion comes just a day after Olaf Henricson-Bell, his twin brother, was made the head of the No 10 policy unit.Meanwhile, Emma Reynolds has replaced Ms Siddiq, who resigned as economic secretary to the Treasury amid allegations of corruption, which she denies.
The MP for Wycombe made a return to Parliament in July after four and a half years, having served as the MP for Wolverhampton North East until 2019.She held several shadow frontbench roles under Mr Miliband, and was the head of the all-party parliamentary group on China.
Before the general election, Ms Reynolds was a member of a City lobbying group that pushed to keep China off the enhanced tier of the foreign influence registration scheme.
The group tried to bolster national security by compelling those working with foreign nations deemed a “potential risk to UK safety” to declare their lobbying activities.
Her lobbying history was reported on by Bloomberg in December when she was still in a more junior Treasury role.
A source told the outlet that she would not be working on China policy at the time. It is unclear if that will remain the position in Ms Reynolds’s new job.
Ms Reynolds’s appointment signals a further attempt by the Government to gain closer financial links with Beijing, and follows Rachel Reeves’s three-day trip that was aimed at boosting economic ties with China in an attempt to help deliver growth for Britain.
