LONDON/MADRID, Feb 6 (Reuters) - TSB, the UK banking arm of Spain's Banco de Sabadell is looking to cut around 300 roles as part of a broad restructuring effort, employee union Unite told Reuters on Tuesday.

The proposed cuts, which were communicated to staff earlier on Tuesday, are expected to fall in the lender's Risk & Finance, Customer Banking and Customer Delivery teams, Unite said.

Spokespeople for TSB or Sabadell were not immediately available for comment.

"Unite is working to support our members impacted by the announcement today," a spokesperson for the union told Reuters.

"The priority of the union is now to reduce the numbers of redundancies, discussing redeployment and re-training opportunities and seeking to ensure any redundancies are voluntary where possible." (Reporting By Sinead Cruise in London and Jesus Aguado in Madrid, editing by Iain Withers)
