Expotel chief executive Ian Burnley, who has worked with departments including Defra and the Department for Work and Pensions, said: "The impact has already been felt. The volume of business is already running around 30% down on last year."
Meanwhile, Eventia has today published a white paper titled Green Shoots Forecast by Britain’s Live Events Sector.
It coincides with Business Visits and Events Partnership’s reception at the House of Commons this evening to drum up support for the events industry from MPs.
Eventia chairman Mark Saxby said: "We fully recognise the scale and threats posed by cuts to public expenditure but also believe it’s vital not to miss the important green shoots and positive indicators for our sector. We need to continue to raise the profile of events to show that they are crucial for businesses, associations and governments to realise their objectives and achieve success."
