There was no minimum term explicitly stated in the memorandum of agreement.
Just to clarify we renewed our lease agreement. The original agreement was a standard contractual agreement.
The tenancy states: "the tenant has the right to terminate the tenancy on 30th September 2015 or a later date by giving a minimum of 2 calendar months prior notice (we did today). However it is agreed that the Tenant may not terminate the Tenancy at any time during the period from the 15th November 2015 and 31st January 2016.
