Landlords Trying to Prevent a Tenant Party

I saw this article about Pete Doherty's poor landlord ( before you feel too much pity - it is the Earl of Cardigon) but it did make me question what rights a landlord has if their tenants decides to have a bit of a knees up.

Do any landlords know about the rights of a landlord who discovers that there tenants are about to hold a party in their rental property.

Is there a way of installing a criteria within the tenancy agreement and how can a party be clearly defined?

ie, Is it a party when a tenant invites a few friends around for a sherry a cucumber sandwiches? (cue joke about Earl of Sandwich)

Anyway I'd love to hear any fellow landlords experience of partying tenants and what if any rights a landlord has to be a party pooper.

If anyones heading to the Pete Doherty gig , I'll see you there. Party on , dudes.
