The British Army has said it is ready to deploy to Ukraine if requested by the government. This week, 2,500 UK troops from the Army's high readiness force, the First Division, have been taking part in a large Nato exercise in Romania - on a training area just 16 miles (25km) from the border with Ukraine.

With the world watching, UK troops in Romania are on the brink of a mission that could alter international dynamics.

The Army is suffering a recruitment crisis and is at its smallest size since the Napoleonic Wars with around 73,000 troops.

Here is what some have said ahead of the meeting on the issue of sending peacekeeping troops into Ukraine. British Prime Minister Keir Starmer has said he is ready to send British troops to Ukraine as part of any postwar peacekeeping force.
