"Rats leaving the sinking ship" is a link to an article in The London Economic (TLE), a left-wing digital newspaper.

Obviously Dave the Gnome has or he would not have provided the link

The actual title of the original article was:
$1 trillion leaves British shores ahead of Brexit D-day.

Needless to say no evidence is provided to back up the assertion!
