Defence Minister James Heappey confirmed this afternoon that further British armed forces are being deployed to Estonia sooner than expected.
In response to an Urgent Question in the House of Commons, Mr Heappey said: "In addition to the Royal Tank Regiment battle group that has been in place in Estonia for the last six months, the Royal Welsh battlegroup will be arriving in Estonia earlier than planned to double up our force levels and those doubled-up force levels remain indefinitely.
"They will be augmented by the headquarters of 12 Mechanised Brigade, meaning that the United Kingdom will have an armoured brigade in Estonia reassuring one of our closest NATO allies."
While he said that "we must all in this House be clear that British and NATO troops should not, must not, play an active role in Ukraine", he said that the Government plans to "explore all that we can do to support the Ukrainians themselves over the next few days."
He added: "We must all be clear what the risk of miscalculation could be and how existential that could very quickly become if people miscalculate and things escalate unnecessarily."
