Britain's difficult geopolitical game has come to Parliament today.

This morning, Mike Johnson, the US Speaker of the House, is in the Commons to showcase the special relationship.

Hours later, in the same building, the Housing Secretary, Steve Reid, will announce the UK's decision on China's mega-embassy in London.

It's one of Beijing's key asks ahead of the UK Prime Minister's planned visit to China later this month.

But the two back-to-back events show the challenge Britain faces in trying to keep both superpowers on side.
