The landlord under a periodic standard contract which arises under section 184(2) (periodic standard contract arising at end of fixed term) may make a possession claim in reliance on—
(a) a possession notice, ...
(b) a notice under section 186,or
(c) a notice under a landlord's break clause,
which the landlord gave to the contract-holder before the end of the fixed term contract.
Sections 179 and 180—
(a) apply to a notice under section 186(1) as they apply to a notice under section 173, and
(b) apply to a possession claim made on the ground in section 186(5) in reliance on such a notice as they apply to a possession claim made on the ground in section 178 in reliance on a notice under section 173.
In any possession notice the landlord gives to the contract-holder, the landlord may rely on events which occurred before the end of the fixed term standard contract.
This section is a fundamental provision which is incorporated as a term of periodic standard contracts which arise under section 184(2).
