Brighton and Hove has staged a remarkable economic revival during the last decade.

After being down in the dumps, it is now a thriving city where visitors, firms and residents want to be.

However, its economy is still fragile and much more work needs to be done to address some of the city's pressing problems.

That is why it's welcome news that many organisations are today signing up to a regeneration strategy which seeks to solve 24 key challenges.

One of them is to broaden the city's economic base which is too reliant on a few key firms. Another is to find attractive locations for new and expanding companies.

Brighton and Hove must also tackle the poverty and deprivation which are still a running sore in areas such as Whitehawk and Moulsecoomb.

At the same time, it must offer training and education to the large numbers of city people who are lacking formal education.

Another pressing problem which has to be addressed is to ensure people taking all the new jobs on offer have access to reasonably-priced housing.

The biggest challenge may be to maintain the flow of cash from the Government and the European Union which has helped towards projects such as restoring the Dome and renovating the seafront.

This in turn has levered in matching funds from private industry which has been hugely welcome. Without it, the city may become a victim of its own success.
