We present an analysis of the X-ray spectral properties of 61 hard X-ray selected (2-8 keV) sources from the bright (f2-8keV > 10-14 erg cm-2 s-1) XMM-Newton/2dF survey. This comprises of 9 XMM-Newton pointings in the North Galactic Pole region ( 1.6deg2) and overlaps with the SDSS, 2QZ and 2dFGRS surveys. Our sources contribute about 50 per cent of the 2-10 keV X-ray background down to the flux limit of 10-14 erg cm-2 s-1. The hardness ratio distribution of the sample suggests a deficit of heavily absorbed sources. A spectral fit to the co-added total source spectrum yields a steep photon index of 1.83{ - 0.05}{ + 0.04} . All but 8 sources have optical counterparts down to the SDSS photometric limit of r ≈ 22.5. Spectroscopic identifications exist for 34 sources. The vast majority are associated with Broad-Line (BL) AGN (24 sources) while only 7 present narrow or no emission lines. Five sources are probably associated with Galactic stars.
