Donald Trump has launched a withering attack on long running comedy sketch show Saturday Night Live in particular skits in which he is portrayed by actor Alec Baldwin.

The US Presidential candidate said the skits are a "hit job" and further evidence of the 'mainstream' media's attempts to gang up on him and rig the election.

For the past few weeks the show has been running a series of sketches featuring Baldwin putting in an uncanny performance as the Presidential nominee alongside SNL regular Kate McKinnon as Hillary Clinton.

Trump has now tweeted his anger over his portrayal in the skits.

Over the weekend the show once again featured a sketch on the two Presidential frontrunners, this time looking back at the second 'town-hall' Presidential debate the previous week.

It made light of the claims by Clinton that Trump was 'stalking' her during the debate and at one point, Baldwin is seen moving around the set menacingly with the Jaws theme playing in the background.

However there were also parts of the sketch that poked fun at Clinton in particular her often-criticised inability to look relateable and relaxed.

Trump's attack on Saturday Night Live is a bit of a change of heart for the former reality TV host and business mogul. Just eleven months ago he hosted the show for the second time, his first stint as host was back in 2004.

Back in 2008 Tina Fey's portrayal of Republican Vice-Presidential candidate Sarah Palin on Saturday Night Live was widely held responsible for discrediting her among voters and helping to fatally damage John McCain's campaign.
