Starmer is attending talks focused on defence and security co-operation and meeting Nato secretary general Mark Rutte.
The trip is part of what he calls a “reset” between the UK and the European Union.
The government has promised the UK will not re-join the EU’s single market or customs union, or sign up to freedom of movement.
But ministers do want what they see as a better relationship on defence and security, crime and trade.
They hope to sort this out by the spring and finalise it at a UK-EU summit, possibly in April or May.
Leaders of the European Union’s 27 member states are gathering for what is described as an “informal retreat” at the Palais d’Egmont in Brussels – a 16th century palace in heart of the Belgian capital.
