Tesla may benefit when founder Elon Musk leaves his government role.  

There are reports the billionaire will leave his role at the Department of Government Efficiency to take a much smaller role in the administration.  

It comes as auto maker reports a 13 percent drop in vehicle sales in the first three months of the year.  

US Correspondent Mitch McCann told Andrew Dickens rumours of Musk's departure are already having an effect on Tesla's fortunes.  

He says it's sent stocks up five percent.
