High Street banking group Barclays said it had made a solid start to the year but warned bad debt provisions were higher than a year ago.

Shares in the bank fell as the caution cast a cloud over news of growth across the group's core business.

In a statement ahead of its interim results in August, Barclays said operating profits in the first quarter were up on a year ago.

Savings and mortgage lending were up, business banking had recorded solid growth and Barclaycard was also ahead.

But costs were also ahead and this spooked investors.
