6(1)For the purposes of this Act a series of linked leases are treated as a single lease—
(a)granted at the time of the grant of the first lease in the series,
(b)for a term equal to the aggregate of the terms of all the leases, and
(c)in consideration of the rent payable under all of the leases.
(2)Two or more leases constitute “a series of linked leases” if they—
(a)are successive leases granted or treated as granted (whether at the same time or at different times) of the same or substantially the same premises, and
(b)are linked transactions.
(3)The grant of later leases in the series is accordingly disregarded for the purposes of this Act except section 51 (return or further return in consequence of later linked transaction).
