No extra Security Needed for Bahrain - Motorsport Chief

Security does not need to be stepped up during the Bahrain Grand Prix, according to the president of the country's Automobile Federation.

The race will return in April - after it was cancelled in 2011 following the deaths of anti-government protesters involved in clashes with authorities.

Button: Lewis my main rival

A week after his near-perfect triumph in Australia, Button was left apologising to McLaren following Sunday's race at Sepang.

The 32-year-old Briton finished 14th in Malaysia after a collision with the HRT of Narain Karthikeyan.

After going into the race with a seven-point cushion over the field, Button now trails Fernando Alonso by 10 following the double world champion's win.

Button, however, does not believe the Spaniard - in a so-far underperforming Ferrari - is a realistic title threat this season.

"Even after such a bad race - and that's hopefully my bad race for the year gone - I'm still only 10 points off the lead, and that's Alonso in a Ferrari. That's not the worry," Button said.

"I'm also only five points behind Lewis, who is the guy in a competitive car, so (it's) still not bad considering the day I had. Lewis is definitely my main rival, and you have to say the Red Bulls as well.

"Those are the guys I still think are the main ones at this point in the season, and will be for quite a few races.

Sebastian Vettel criticises ‘idiot’ backmarker in Malaysian GP

Sebastian Vettel described one of the backmarkers in the Malaysian Grand Prix as an "idiot" after a collision cost him fourth place.

The world champion got a puncture while lapping Narain Karthikeyan's HRT and dropped back to finish 11th.

"Like on normal roads, you have some idiots driving around. It seems there is also one driving here," the Red Bull driver said.

Karthikeyan said some leading drivers try to "bully" backmarkers.

Neither man mentioned the other by name, although it appeared clear who they were talking about.

The incident happened on lap 46, with 10 laps to go, as Vettel was chasing Lewis Hamilton's McLaren for the final podium place behind Ferrari's Fernando Alonso and Sauber's Sergio Perez.

Vettel passed Karthikeyan on the back straight at the Sepang track but the two collided as the Indian moved back towards the racing line.

Red Bull team principal Christian Horner said it was Karthikeyan's "responsibility to get out of the way of the leaders as he is a lapped car".

Karthikeyan said: "With Vettel, I got on to the marbles and the car had a lot of wheelspin.

"I had to jink to get out of it and unfortunately he was there. What else I could I do?

"Some of these guys when you get lapped, they just try and bully you so much, it's not fair.

"I won't mention names but sometimes they overtake you and they want you to go off the road.

"With this car it's a big task to qualify and to finish is a big task. We're a small team. We don't want to be a hindrance but doesn't give them the right to bully you. This is not right. "

Karthikeyan was also involved in an incident earlier in the race in which McLaren's Jenson Button collided with the HRT and lost his front wing.

They were racing for 15th place at the time and Button acknowledged it was his fault.

"I can't do anything but laugh really because it was such a horrendous race," Button said after finishing 14th.

"I didn't do a very good job and everything that could have gone wrong did. Just one of those afternoons.

"A lot of the issues were because I wiped my front wing off, locked up my rears and couldn't slow down."
