British consumers may have to pay over 20 per cent more than their US counterparts to get their hands on Apple's new iPad tablet, it has been suggested.

New estimates from VoucherCodes.co.uk revealed that, over the last decade, Apple products launched in the UK have cost an average of 22 per cent more than on the other side of the Atlantic.

This has led the website to predict the iPad, which is expected to be available on a range of broadband deals from providers including Vodafone, Orange and O2, will retail at £399.

Last week, Apple confirmed it had put back its international launch of the iPad for one month.

The computing giant claimed that demand in the US had exceeded expectations and the success has forced its hand over its release in other countries.

Over 300,000 units of the tablet device were sold on the first day of its launch.
