Yes you can leave them Liz. The daffodils will definitely come up again next year and will slowly increase in numbers. Some of the tulips will reappear next year too but not all of them. Generally, the more 'fancy' the tulip, the less chance of it flowering again. If you plant them deep (about 8 inches = 20cm) the better chance of repeating. It's best to treat 'fancy' tulips as annuals and plant new bulbs in early winter each year. If you want colour co-ordinated displays then it's best to lift tulips otherwise you'll end up with random survivors popping up. My whole garden is 'cottage' style so I actually see that as a bonus.
