Cook leeks in boiling salted water for about 6 minutes until just tender but still firm.
Meanwhile, in a bowl, mix together red pepper (capsicum), vinegar, oil, sugar, paprika, salt and pepper.
Drain leeks well, briefly lay on absorbent kitchen paper to absorb excess moisture, then place in a warm, shallow dish
.
Pour over vinegar mixture, turn leeks to coat well, then cover and leave for a few hours in a cool place, turning leeks occasionally. Garnish with chopped parsley, capers, if using, and black olives.
