If someone built a space port in the Canary Islands that would actually be at a similar latitude to Cape Canaveral, though the latitude of French Guiana is hard to beat (and the Canary Islands are technically part of Africa, not Europe).
Morocco might also not be very happy with this. Generally, your ideal site for equatorial launches has ~nothing to the east, for a long way. There's a reason that ESA uses the (on the face of it ridiculously inconvenient) French Guiana facility.
