Westminster Cathedral "went along with it" because Johnson and Symonds live in its parachial area and, having never had a previous catholic marriage, there could - as the Archdiocese has pointed out - be no objection (apart from a few people who don't seem to understand the rules).
I think it’s time that you stopped (1) being insulting and (2) embarrassing yourself.
You produced a piece of evidence in support of your position, which is that the Catholic Church will ignore all previous marriages if they took place outside the Catholic Church. Hence, according to you, no annulment was necessary.
You then declared that I couldn’t be Catholic, thought I knew better than the Westminster diocese, etc. You’re clearly not somebody who can argue in a civilised way.
You added a link to Father Gary Dench’s statement to the Irish Times which, you claimed, proved that previous non-Catholic marriages would be ignored and that no annulment was needed.
Wrong. Your own evidence contradicted your position, because Father Dench explicitly stated that a prior marriage of any kind - religious or civil - would be an impediment to a Catholic marriage unless the prior marriage was declared null and void.
Here is the quote again:
Another impediment would be a previous marriage, whether conducted in the Catholic Church, in another church, or by the State, and not yet declared null and void
The mechanism for declaring a marriage null and void is an annulment, which nobody is given automatically unless the circumstances are extreme (e.g. the marriage took place under duress, or one of the parties was underage).
So yes, they would have needed an annulment. As your own evidence confirms. It’s difficult to see why you can’t accept that. Perhaps it is embarrassment, because you have tripped yourself up.
