Thank you all, I have tried everything you have suggested, the door jamb didn’t work for me, couldn’t find my pliers and yes I have pushed it down press the two sides together everything I should do, and actually it is very difficult to cut through those little white plastic things that are holding the lid on it really is But after much effort and some very choice language I did manage to cut through the two main “structures “.finally my daughter in law managed to do it. What I want to know is why is easier to get into a bottle of vodka than it is to get into a bottle of mouthwash? I was seriously thinking of taking it down to customer service at Tesco’s and saying please can you open this!!
