No. Your prospective employers are not allowed to discriminate against you because you are married, and if they did they would be in breach of discrimination law. You may have an employment tribunal claim against your husband's company, though this is unlikely to help you actually get an advertised job, as it’s a long process. It might also not be the most harmonious way to start a new job if the first time you meet your boss is in court.
Get advice from your union or your husband's union, if either of you are union members. It may be possible for you or them to talk with the company and ensure they consider your job application fairly, without having to involve the law.
