Fixed caps on publicly funded immigration work were introduced in April 2004 which means that legal representatives are now only able to carry out five hours of work on a file before applying for an extension.

It has also been noted that a significant proportion of asylum seekers reaching the end of the asylum process lose their case because they have not received proper advice but are unable to secure.
