UK-headquartered advertising agency M&C Saatchi has reported a rise in revenues and profits for the first half of the year.

However, it warns storm clouds could be on the horizon if there is an unfavorable outcome to the review of its British Airways account.

The agency says pre-tax profit for the six months to June 30 rose 1.7% to £4.1 million ($7.4m; €6m), and like-for-like revenues were up 7.1% to £31.9m.

Comments ceo David Kershaw: "The outlook for the full year is positive and in line with our expectations. However, the outcome of the review of the BA account could have a major influence on performance in the second half and beyond."

Agency founders, Charles and Maurice Saatchi, have helped run the £60m global ad account for around 23 years, and it makes up around 6% of the company's total revenues.

In the running for the business are WPP's JWT, Omnicom's DDB and Bartle Bogle Hegarty, partly owned by France's Publicis. A decision is expected in mid-October.
