David Morris recieved a donation from Aquind Ltd, which is seeking to build a £1.1 billion electricity cable linking the UK and France

A Conservative candidate received a £10,000 donation from an infrastructure company before asking a question in the Commons about regulations affecting the firm.

David Morris, a backbench MP since 2010, was given the money by Aquind Ltd in September and a month later he asked the government to lobby Ofgem to make regulations which would benefit the company, in an apparent breach of lobbying rules. Aquind is seeking to build a £1.1 billion electricity cable linking the UK and France.

The guide to the members’ code of conduct says MPs must not “initiate a proceeding or approach which seeks to confer any financial or material benefit on an identifiable person from whom or an identifiable organisation from which they have received outside reward or consideration”.
