""Xenophobia in this context would have to be a fear of foreign immigrants and thus racism.""

Xenophobia, in any context, is fear of foreigners, whether they be in England or Abroad.

It is independent of their location, and therefor the correct descriptor in this case is bias against immigrants.

Racism may not be the appropriate single word for this, but it will have to do until somebody invents a better one.
