Hi marodj, I think t is probably a cordyline australis which isn't a true palm but most folk call them palms in the UK. If it is, the good news is that it will almost certainly sprout new growth from the base now that the trunk has been severed. To help stop disease entering the damaged trunk, I would cut it cleanly a few inches below where the top broke off. Once the new shoots have grown a couple of feet high I think you would be safe to cut the old trunk off at ground level and if you want just one new trunk, select the strongest new one and remove the rest. You could also let all of the new shoots grow and have a multi-stemmed one.
