HC Deb 13 March 1986 vol 93 c546W
Mr. Nicholas Baker

asked the Paymaster General if he will introduce legislation imposing a requirement that companies obtaining work permits for the employment of foreign nationals should state what steps they will take to train a citizen of the United Kingdom to take over the job at the expiry of the work permit.

Mr. Lang

In many cases it is not practical to fix an expiry date, nor is it always reasonable to expect the employer to replace the overseas worker.
