GroupM, the media buying arm of WPP, has forecast the highest UK advertising spend since the economic crash and subsequent financial crisis of 2008 in their report 'This Year, Next Year UK'.

Negotiations between WPP's media buying division Group M and broadcaster Channel 4 have come to a standstill as Sir Martin Sorrell's advertising group seek an improvement on their two-year, £200m deal that expires before 2013.

The Internet Advertising Bureau's latest report into advertising expenditure has revealed a 12.6% rise in digital ad-spend totalling £2.6bn for the first six months of 2012, up £294m from £2.3bn in the previous year.
