The site's publisher, Ben Wegg-Prosser, said: 'We will be building on the reputation we have established in Westminster and beyond for breaking news.'
Glover will maintain an executive editor role on the website, which Wegg-Prosser said will mean greater tie-up between the newspaper and the site. 'During the election, we worked quite closely together,' he said.
In 2001, MPs, readers and voters were asked for their views on Labour's performance, which were published online and in print. 'We will do more of those sorts of features,' Wegg-Prosser said.
Happold, who is in charge of a three-strong editorial team, said: 'With elections coming up in Scotland and Wales, along with the decision on the euro and the possibility of another Tory leadership campaign there will be much to keep us busy.'
Wegg-Prosser said that there were ongoing opportunities for PROs on the site: 'We are always looking for views from people within the industry who have interesting ideas on presenting their views to Parliament, running local and national campaigns and putting things across to political opinion-formers.'
He added that upcoming events, such as the Budget and party conferences could be useful to people 'who are looking to communicate with our audience'.
The online network launched its politics site in March 2001, two months before the last general election.
Happold began his broadcasting career in 1995 as a researcher on Channel 4's A Week in Politics. Prior to joining the BBC News at Ten he worked on Channel 4 News, and a variety of politics documentaries.
Wegg-Prosser is also general manager of the Education site, which is edited by Jimmy Leach.
