Why am I on a march where this is the chant?'\"\n\nHe added: \"I'm not saying, of course, that there aren't very strong legitimate views about the Middle East, about Gaza.\n\n\"We all have deep concerns about it. This Government has recognised Palestine just last year. So, of course, there are important issues,\" he added.\n\n###\n\n\n\n\n\n\n\n\n\n\n**Our Standards: The GB News Editorial Charter**",
