I thank the hon. Gentleman for his question, although it is one for the Minister, rather than me. I would certainly expect the authorities to use the power proportionately and where necessary to keep people safe, not to stop and question people at the border without reasonable grounds.
Several hon. Members have raised the “reasonable excuse” issue in respect of people returning to this country. People who have been to a declared area will have the “reasonable excuse” defence. So people will be able to travel to these areas for legitimate purposes—for example, for journalism or to visit family for a funeral or some such important bereavement event. It will also be allowed for people delivering aid, and obviously for the armed forces. The Government have worked to ensure that these “declared areas” provisions meet the important test of protecting our citizens and are both proportionate and effective.
