Hi thanks for your question i will assist you with this. I am afraid to say that if you have never divorced or applied to annul this marriage then you cannot marry again without first resolving this previous marriage as in the eyes of the law, you are already married. There are grounds under section 12 of the Matrimonial Causes Act 1973 to void the marriage on the basis of incapacity to consummate the marriage, but I would recommend you obtain legal representation to assist you to do this. Please see this link which is to a government website which explains this and the process fully - https://www.gov.uk/how-to-annul-marriage. If you have any further questions please don't hesitate to come back to me.
