In the UK and Ireland, the Financial Times sold 132,178 copies, 74,123 of them were at full price. The U.S. edition, however, was the biggest seller among all FT regional titles, selling 130,841 copies.

"The sustained strength of the FT's circulation underlines the quality of its journalism and the fact that we are a must read for the international business community - particularly at a time of turmoil in the markets," John Ridding, the chief executive of the Financial Times told MediaGuardian.

The Independent fell most seriously among all quality national dailies, recording a 5.89 percent of year-on-year circulation decline to 239,834 copies, with a 0.12 percent month-on-month slip.

The Indy, followed closely by the Times, had a year-on-year circulation fall of 5.36 percent to 638,820 copies, a small increase of 0.5 percent over July.

The Guardian recorded declines both year-on-year and month-on-month, with 1.96 percent and 1.81 percent falls respectively. The newspaper sold 355,750 copies in August.

The Daily Telegraph also fell across the board, although smaller, with a 0.18 percent of month-on-month dip and a 1.18 percent of year-on-year slide, to 887,664 copies.
