Twitter UK is the wholly owned subsidiary of Twitter International Company, an affiliate company of Twitter, Inc. Twitter UK provides marketing and sales support services to Twitter International in connection with sales of advertising to customers in the UK. In a voluntary statement, it made clear that Twitter UK had no control over the Twitter service. At the time of giving evidence, Twitter had not blocked content to users in the UK which people in other countries could see. Twitter would consider whether such an action was necessary on a case-by-case basis.
