Jeremy Hunt is set to unveil his so-called "back-to-work budget", bringing in measures aimed at tackling labour shortages in the UK.
The Chancellor is expected to bring in a string of controversial measures, which have sparked fears that people with long-term health conditions could be forced into "unsuitable work".
Mr Hunt was brought in by Liz Truss to steady the ship after Kwasi Kwarteng's disastrous spell in the Treasury came to an abrupt end last October.
