The new-look show with presenters Chris Evans and former 'Friends' star Matt LeBlanc was expected to air on May 8, but now it has been delayed until May 22, and has also been cut from being an eight-part series to six.

A BBC spokesman commented: "We've always said we were working towards a May transmission for 'Top Gear' and further detail on the date and series structure will follow nearer the time."

While it's unsure why the programme has been delayed, there have been several setbacks including, the exit of the motoring show's executive producer Lisa Clark.

It has also been reported that the reason for her departure is down to Chris, 49, not committing 100 percent to the motoring show and him saying that she was "undermining him" about not doing "enough" on a segment he'd filmed with racing ace Jenson Button.

A source told The Sun newspaper: "Evans didn't normally turn up to a lot of meetings, but at this one he said he had completed some footage with Jenson Button.

"Lisa replied, 'Yes but we need to make more than 30 films. It's not enough'. He shot her a look for undermining him and she was soon gone."

Meanwhile, the insider added that Chris wasn't happy about Matt being a presenter because he's "old hat".

The source added: "It was Lisa who suggested Matt, but Evans' reply was, 'He's old hat, what do we want him for?'."

The BBC have declined to comment on Lisa's exit.
