LONDON – A secret briefing document held by an individual walking into Downing Street suggest that the UK will oppose trade sanctions against Russia following the country's invasion of Ukraine.

The document, captured on Monday by freelance photographer Steve Back of Political Pictures, also suggests that the UK will not seek to restrict the ability of Russians to use Britain as a financial centre.

However, the document does suggest that the UK is considering whether to place visa restrictions on certain key Russian figures.

Thousands of wealthy Russians have settled in London since the end of the Cold War, investing millions into property and other businesses.

The individual arrived at Downing Street ahead of a meeting of the national security council called to discuss the ongoing Ukraine crisis.
