2.—(1) This paragraph shall apply where a pension payable to the widow of a serviceman in pursuance of paragraph (1) or (3) of Regulation I3 is increased in pursuance of paragraph (5) of that Regulation.
(2) The increased amount of the pension payable to the widow for any period shall not, when aggregated with the amount of any armed forces award which is also so payable for that period in respect of her husband, exceed the amount of the pension which would have been payable for that period if the injury as a result of which her husband had died had been treated as if it were an injury received without his own default in the execution of his duty as a regular policeman.
