Chris Evans will not be presenting any more series of TFI Friday for Channel 4 as he throws his efforts into his new role as Top Gear host.

A source confirmed there were 'no plans' for the show to return, which he first hosted from 1996 to 2000 and again over the past autumn.

Evans's attention instead will be on Top Gear which returns in early May with him at the helm, alongside German racing driver Sabine Schmitz, journalist Chris Harris and F1 driver David Coulthard.

It is claimed Chris Evans has been 'overcommitted', with BBC bosses surprised he took on his Radio 2 show as well as Top Gear

Chris Evans will no longer present the Channel 4 show TGI Friday due to his new Top Gear workload

They replace Jeremy Clarkson, Richard Hammond and James May who left the show when Clarkson's contract was not renewed after he punched a producer.

Meanwhile, The Sunday Times has reported that preparations for the show are 'in a shambles'.

The paper reported Evans had been 'overcommitted', with BBC bosses surprised he took on his Radio 2 show as well as Top Gear.

Evans has been pre-recording segments and admitted in a recent magazine column that he had worked for 26 hours straight one day covering his BBC Radio 2 show TFI Friday and Top Gear.

He wrote: 'It began with the usual 4.30am Friday start for the Breakfast Show.

'After that, it was straight to TFI Friday. All I could think of was my third job of the day, jumping on a motorbike the moment TFI finished.

'I got back home at 6.40am on Saturday, - 26 hours and 10 minutes after my alarm had gone off.'

A source close to Top Gear is reported as saying: 'Chris has been overcommitted, with even BBC bosses surprised that he took on TFI as well as Top Gear. The pressure on him has been immense.'

Losing the knowledgeable production team behind the show has also caused teething troubles.

The source added: 'They've brought in a production team that doesn't know anything about cars. Writers from Top Gear magazine have had to be called over to suggest ideas and offer advice on what cars to film.'

The latest blow for Evans was the loss of his long-time colleague Lisa Clark, just five months after she had been brought in as executive producer on Top Gear. The show's script editor Tom Ford is also departing.

Clarkson, Hammond and May are headed over to Amazon Prime to present an as-yet-untitled motoring show next year.
