MacKay was press secretary to former Tory leader William Hague from 1997-99 and advised John Major during the then PM's leadership election in 1995. He also worked at Hill & Knowlton and joined Media Strategy in 1999.
Media Strategy MD Charles Lewington said: 'We have lost a good friend as well as a great professional. He was a natural at this job, building a really strong team. It's our responsibility to take forward that brilliant legacy.'
