look bredrin let me break it down for people who are limited to first derivative thinking.
1st. breh got a high profile high seat in uk politics -
you probably managed this step all by yourself
2nd. breh chancellor is going to be on TV and in media
3rd. that news will be broadcast internationally
4th. he will attend intrernational fora
5th. that news will be broadcast internationally
6th. as a minimum the sight of a breh as an interntaional authority figure of a leading nation will push back against commonly held notions about breh ability in europe.
addendum I: you know like how imagery of indians running the biggest global IT companies helps their profile.
addendum II: this is irrespective of local internal UK politics
focus on one conceptual abstract reasoning step at a time breh and you should be able to follow
it's pretty simple really.
