Can owner ask to vacate flat without any valid reasons

I'm living in a rented premises & have entered into a lease and license agreement with the owner. The owner has asked me to vacate the flat without giving any reasons. I'm living in that flat for more than a year now & the owner might want to rent it to someone else. As per our agreement, both parties can give 2 months notice for vacating. Is it correct from owners side to ask me to vacate? If yes, then can I ask for the agreement cost which I had paid during the agreement creation.
