I sensed that my hon. Friend was heading to a conclusion. At the beginning of his speech, he said how important the port of Southampton is for the wellbeing of the city, so will he confirm that this is not an attack on shipping, which is a fundamental industry for the UK economy? Members want to support shipping and are asking the Government for leadership in ensuring that shipping is more environmentally friendly and clean in the future. That will mean that when new cruise terminals are proposed for places such as the centre of London, people will welcome that because of the economic benefit it will bring and because they know that it will operate on an environmentally clean basis.
