THE impact of Britain's heatwave will be in sharp focus this week when Thomas Cook and TUI Travel report back from the holiday sector, while Irn Bru maker AG Barr and pub group Mitchells & Butlers update on drink sales.

Holiday giants Thomas Cook and First Choice owner TUI Travel will go head-to-head on Thursday when they update on summer trading.

TUI saw UK summer sales growth ease slightly as July's heatwave hurt last-minute getaways, but is benefiting overall from growing consumer confidence.

AG Barr, based in Cumbernauld, is expected to report a summer of fizzing sales, lifted by the UK heatwave.

Revenues are expected to have surged almost 10% in its second quarter. That is expected to have lifted first-half sales 4.9% to £127.5m.

Mitchells & Butlers, the UK's biggest operator of managed pubs, unveils latest trading figures on Thursday amid an £80m investment drive by the group.

M&B, which has about 1600 restaurants and pubs, recorded drink sales up 2.7% in the 14 weeks to July 20.
