Hi Len,
Something is not right there. Can you let me know which gates you used if possible. I’m assuming somewhere in the vicinity of platform 8/9 first and 4/5 second. I’ve an idea for a FOI request which might highlight the issue but I want to narrow it down first.
I went through London Bridge myself twice on Saturday and the times seemed to be appropriate, so if there was an issue it looks like it’s been fixed.
