To ask the Chancellor of the Exchequer when he will reply to the letter of 12 March from the hon. Member for East Worthing and Shoreham on the small and medium enterprises threshold for the purposes of the research and development tax credit in relation to Allergy Therapeutics in Worthing. (207141)

As I believe the hon. Member knows, the Treasury has no record of having received his letter. A copy has been requested and will be dealt with as soon as possible.
