The idea that this is the “main” problem in the UK is frankly laughable.
Controversially, https://en.wikipedia.org/wiki/Evgeny_Lebedev has been ennobled and is now qualified to sit in the House of Lords, most definitely a position of power though he has not as yet chosen to appear there as far as I know.

The rabbit hole goes deeper, keep digging! They can't keep the truth hidden forever.
The only surprise here is that he's Labour, not Tory.
Half of the current Great Offices of State are held by brown people under the Tories, who also had the first Jewish PM, the first (and second, and only) female PMs, and then there's Saj who's been Chancellor and Home Secretary, and I reckon is about as likely as Sunak to be the next PM. They appointed the first female, gay head of the Met Police, and the leader of the party in Scotland was also a gay woman for 8 very recent years.
Some of these people are clearly the worst of British politics (hello Priti Patel!), but the Tories have an excellent record of putting people who aren't straight, white, Christian men into positions of power.
It is quite likely the next PM will be of Pakistani or Indian ancestry (unless it’s a Labour PM; they have a poor record of promoting minorities to the top of Government) It's simply not true that the UK is xenophobic.
What on Earth are you talking about?
10% of parliament are from ethnic minorities (including many high profile positions, Tories included), against a UK background of 14%.
