Uk agrees to host on behalf of ukraine

I think there may be some confusion here!

The UK has not agreed to host anything on behalf of Ukraine. Could you please provide more context or clarify what you mean by "host on behalf of Ukraine"?

Are you referring to a specific event, organization, or initiative? Or perhaps a diplomatic agreement or partnership between the UK and Ukraine?

If you have any more information or clarification, I'd be happy to help you understand the situation better!
