Well I went ahead and deleted /dev/sda3 using gparted and as you
suggested the partition numbers of remaining partitions were
unaffected (sda3 being a primary partition), so it had no effect on
booting or anything else.  Possibly my memory was incorrect in
thinking that I had previously had a problem with this.  I have now
also moved and resized the other partitions to make the space
available to them (which was the point of the exercise).

Thanks to everyone for the help
