Well, the Daily Mail, or as I prefer to call it, the Daily Malicious, has had a go at an immigrant who served in the Royal Navy in the second world war, for what he wrote when he was a teenager, and (shock horror) for having left wing views. This is a paper which has supported fascism. A paper which from what I understand has yet to apologise for this view. An issue which has been raised by many, including those in the Conservative Party.
While there are many issues in the hate ridden article that they published, the facts are simple. The Mail owned by by Lord Rothmere, who supported Hitler in the 1930's was a supporter of the far right. Ralph Miliband was against Hitler and fascism and served our nation in the fight against them. Make of that what you will.
