This being an post complaining about weather in London, English law can be assumed to apply. First of all consult a local solicitor in employment law. Collect all your reviews and e-mails about your job performance in the last years. The solicitor can tell you what your risks are as losing a job can be a big financial problem. This will cost you a 100 to 300 GBP which is worth it. (have a look around see if a trade union can help you for much less) Then document what is going on with the secret project and if possible show where your boss has lied on paper/e-mail. Then either schedule a meeting with your bosses boss and ask internal legal council to be present if it is in your company do this personally and make sure the meeting is on short notice and preferably early in the day. If possible have a basic recovery plan available but do not give it unless asked for it. You should show concern for the business not look like you want your bosses job. During this period of course look for new opportunities elsewere as, if your current boss stays your boss work is not going to be any fun. Even if they can't fire you now.
