'Bodyguard' creator Jed Mercurio in talks for a second season but hopes for four more after show's ratings soar

After it's successful first run, the BBC 1 hit 'Bodyguard', starring Richard Madden, might be stretched out for four seasons long-series. The show has been so intriguing that around 10.4m people (11m peak, 47.9% share) had tuned in for the finale which gave the episode the largest viewership since the periodical drama 'Downtown Abbey', which had aired on ITV in November 2011, with almost 10.6 million viewers.
While Twitter almost faced a meltdown following the finale, viewers have already begun their speculations regarding the title of the upcoming seasons in the series. In an exclusive interview with The Sun, writer Jed Mercurio mentioned that he would want the series to go up to at least four seasons, just like his previous show, 'Line of Duty', which already has four seasons and will probably get two more. Mercurio said, "We have been very fortunate with the success of series one. It’s probably fair to say we would probably approach any thoughts of a second series with the idea that it would create an opportunity for a third or fourth.”
