asked the Secretary of State for Industry what use has been made of article 90 of the Rome Treaty to date; and whether there are any comparable provisions in the Treaty of Paris.

I am not aware of any use which has been made of article 90 of the Treaty of Rome to date. There are no directly comparable provisions in the Treaty of Paris, but, under that Treaty, the Commission has certain powers to ensure that the Treaty objectives relating to competition policy are attained.
