I mean, if we're talking about people not born in the UK being elected to political positions in the UK...
I've met Nus Ghani, the current Deputy Speaker of the House of Commons. I quite liked her. She was born in Kashmir, but grew up in Birmingham. Her constituency (rural, overwhelmingly white) has elected her multiple times with big majorities.
Nus knows that there's a problem with integrating minorities. The second time she was elected an MP, she got permission from the Speaker to take the oath in Urdu, because her mum would be watching and she didn't want her mum to have to ask a male family member to interpret for her.
I believe she's also married to an English bloke. If you're married into the tribe, you're part of the tribe as far as I'm concerned. (See also: Kemi Badenoch)
There are people on X who take huge offence to Nus Ghani having a role in political life. These are precisely the same people who like to slam Reform for having Zia Yusuf in a leading role. These people are absolute poison.
There are lots of people who may not be ethnically British but love the country they live in. There are some who don't, which is a problem. It's not really about race, it's about how people position themselves towards the country they live in and their fellow citizens.
It can get complicated. I don't like Muslim sectarian voting that elects MPs on their attitude to Gaza, but Adnan Hussain is an interesting guy who's been thinking about how working class Muslims in Blackburn have a lot in common with working class white people in Blackburn. I can see myself having a useful conversation with him. Maybe less so with senior Tory Bob Blackman, who invited a bunch of his Hindu constituents to Parliament for a celebration of Modi's birthday.
Lord alone knows what Rupert Lowe thinks about this, but as I've said, I think "Restore" - to the extent it has any ideology - will be defined by the angry young men who Rupert has hired to run his social media.
