monobloc tap

Hi guys, I had a drip from my Deluxe chrome monobloc tap. I fixed it by removing the cold tap side and replacing washer. Now water is leaking from bottom of base. Shining torch at base and switching on tap you can see water leaking from the base. I've attached a photo. How do I fix this...
