Woo Hoo - Space problem all sorted! I am going to jab my leeks in around my few parsnips and acrrots, use the space i was saving for my leeks for my sweetcorn, use the space i was going to use for my sweetcorn for the rest of my brassicas, wait for my peas to finish and put in my over winter brassicas  there and then the onions will be ready for harvest and ill green manure there! Few - glad i got that sorted!!!
