Clause 4.3.1 has now changed to disallow the customer from cancelling their contract if "we give you written notice to increase the charges (as a percentage) by an amount equal to or less than the percentage increase in the All Items Index of Retail Prices or any other statistical measure of inflation published by any government body authorised to publish measures of inflation from time to time, and published on a date as close as reasonably possible before the date on which we send you written notice". This led to many customers using the change of clause to cancel their mobile phone contracts with Orange.
