The Conservatives have opened up their biggest lead over Labour since before the 2010 general election, according to a new opinion poll.

Ipsos MORI put the Tories on a huge 47 per cent - seven points up on last month and 18 points ahead of Labour who dropped five points to 29 per cent.

Figures showed the Liberal Democrats are up one point on seven per cent, overtaking Ukip who are down three on six per cent.

The findings will alarm those Labour MPs who fear the party cannot win a general election under Jeremy Corbyn, despite his overwhelming victory in last month's leadership contest.

The poll found just 31 per cent were satisfied with the way the Labour leader was doing his job against 55 per cent who were dissatisfied.

It gave him an overall negative satisfaction rating of -24.

That contrasts with Theresa May who enjoyed a positive satisfaction rating of +16, with 48 per cent satisfied and 32 per cent dissatisfied with her performance.

For the poll, Ipsos MORI interviewed 1,016 adults aged 18 and over across Great Britain by telephone between October 14 and 17.
