CWU members have overwhelmingly agreed to retain the union's Political Fund in a ballot which saw a Yes vote of nearly 87 per cent.
Political Funds allow trade unions to have a political voice and campaign on issues that affect their members.
All unions are required by law to hold a full postal ballot of their membership every ten years to confirm the retention of their Political Fund.
Billy Hayes, CWU general secretary wrote:"This is a great endorsement by our membership of our Political Fund."
