You can't get 'Cyprus sherry' any longer because the word 'sherry' has protected status and must now only be used to describe wines from the Jerez region of Spain.
Although 'true' sherry uses the same grapes (Palomino) as Emva Cream did, it's unlikely that you'll easily find any that are as sweet as it. Rather than look for anything labelled as 'sherry' you might do better by seeking an alternative fortified wine. If you're lucky enough to have a good quality wine merchant near to you, it might be worth looking for a bottle of Commandaria (which is a sweet, fortified wine from Cyprus). Alternatively look for a Madeira bearing the word 'Malsmey' (or 'Malvasia') on the label, as that grape produces the sweetest fortified wines from the island.
However if you want to stick with sherry, look for a sweet Oloroso or (if you like really sweet sherry) a Pedro Ximénez.
Sainsbury's Olorosa Reserva Medium Sweet Sherry, at £6.99, might be suitable, as would their Taste the Difference 12 Year Old Sweet Pedro Ximenez at £7.99.
