1. Dear Simon, both your children can apply for a British citizenship based on their birth in England. Here is a link to the UK Government website which explains the situation where a child has been born in the UK since 1983 https://www.gov.uk/register-british-citizen/born-in-uk-after-1983. There is a link to form MN1 which you can fill in for each of your two children. I don't know who advise you that you couldn't get a passport but both are eligible to apply for a passport based on your UK citizenship.
