It’s been a pretty dreadful week for security at the Palace of Westminster. First, there was the admission that a Chinese spy suspect, Christine Lee, had donated thousands of pounds to Barry Gardiner’s office where her son, Daniel Wilkes, was employed as a member of staff. His access to the parliamentary estate was not revoked until he resigned yesterday, with Wilkes still being listed as a member of Gardiner’s Microsoft Teams group as recently as last night.
