[11] It is plain from the second defendant's outline of argument that there was no misapprehension as to this. The third party's argument proceeds on a concession, for the purposes of the application only, that there is no disputed fact and that any factual matter which the second defendant may wish to establish against the third party, within the parameters of its pleading and particulars may, for the purposes of the argument, be accepted as true. In particular, for the purposes of the application the argument should proceed on the footing that the second defendant is a "principal" for the purposes of sub-paragraph (d) of the definition of "you" and that the third party will establish the factual matters particularised in its proposed amended statement of claim (filed by leave before me) and previously supplied further and better particulars.
