16.04 – What is the minimum space needed for Ubuntu 16.04LTS 32bit? Do I need a linux swap also?

I am severely limited on my main hdd, as /dev/sda1 (windows 7) is 59.51gib with a 2gib linux swap, and a 13gib /dev/sda2 ext4 where I had an installation of Arch 32. Is it possible install Ubuntu 16.04lts 32 in same partition?
Do I still need the 2g swap to run Ubuntu? Thanks David
