But in the mid-2000s, they did try to do something 'special' with the Sunday 9 - 10am slot on BBC 1 over the summer. Who remembers "News 24 Sunday" with Peter Sissons?

According to Genome it ran until 2007. After that the idea of the main Sunday morning show going off air for 6 weeks or so was reduced to a shorter 2/3 week break for a few years

In 2008 there was Summer break for The Andrew Marr Show, but just for three Sundays during the Beijing Olympics. Zainab Badawi presented one show on 3rd August, with Andrew Marr returning on 31st August genome.ch.bbc.co.uk 
Presumably with the Olympics taking up three weeks, it was decided there was no point in having a News 24 Sunday that year

2009 saw The Andrew Marr Show run as late as 16th August before being replaced by BBC News for 2 weeks. Again guest presenters for two of the August editions. 2010 and 2011 The Andrew Marr Show ran until 8th and 7th August respectively, and again with guest presenters for the final shows before the Summer.
