Jeremy Corbyn is hoping to persuade Ed Miliband to return to frontline politics and accept a job in the Shadow Cabinet, it emerged today.

But the move has already caused a backlash among MPs, who are angry at the prospect of Mr Miliband taking an influential role so soon after delivering Labour's worst election performance in more than 30 years.

Labour moderates also blame him for introducing new rules to the voting procedure for electing the party's leader - which helped Mr Corbyn to storm to a landslide victory last September.

Mr Miliband's reforms allowed 'registered supporters' who signed up for £3 to have a vote in the Labour leadership elections - many of whom were more left-wing than ordinary party members at the time.

Mr Miliband has been advising Mr Corbyn on a range of issues in private, according to reports in The Times.

His advice includes how to deal with a hostile media - something both men have faced in abundance over the last few years.

Now Mr Corbyn are confident they can persuade Mr Miliband to join his top team - despite turning down a role in the shadow cabinet when the radical left-winger was first elected leader in September.

The move by Corbyn allies to woo Ed Miliband (pictured delivering his resignation speech after last May's crushing defeat) has already caused a backlash among MPs, who are angry at the prospect of Mr Miliband taking an influential role so soon after delivering Labour's worst election performance in more than 30 years

It is part of the leadership's plan to tighten its grip on the party after speculation that moderates were planning to launch a leadership challenge this summer.

Mr Miliband was understood to be reluctant to returning to frontbench politics so soon after his crushing defeat in last May's general election.

One former Labour frontbencher told The Times: 'Ed shouldn't be in the shadow cabinet... he should be in jail for what he did to the Labour party.'

Mr Corbyn's allies are thought to be plotting to remove his critics from the Shadow Cabinet after June's EU referendum and replace them with 'true believers'.

One MP claimed Mr Miliband 'agrees with more of Jeremy's programme for change than he agreed with the stuff he was doing when he was leader himself'.

On Saturday Mr Corbyn told the party that it must be ready to fight a general election before 2020.

He raised the prospect of an early election, claiming David Cameron's Tory Government could collapse over its deep splits on Europe.

The Labour leader set out plans to revolutionise the way the economy is run - telling party members that they may be able to implement them earlier than expected.

But senior Labour MPs have warned that the party risked losing more support to Ukip if it failed to deal with the impact of mass immigration.

Today Chuka Umunna made a hard-hitting intervention warning that the failure to tackle ethnic divisions is creating widening 'cracks in our communities'.

And he even warned that Britain could elect a 'Donald Trump-style' leader unless mainstream politicians deal with increasing ethnic segregation.

It followed warnings from former Labour frontbencher Tristram Hunt, who said yesterday that the party 'risks losing the next general election and looking like a “Southern cosmopolitan” party if it fails to address voters’ concerns about immigration’.

The Stoke-on-Trent MP said Labour will lose another general election if it ignores the ‘dramatic changes’ immigration has prompted in some communities, particularly in the north.

Last week shadow Europe minister Pat Glass was forced to apologise after being caught on microphone describing a voter who referred to a Polish family as ‘scroungers’ as a ‘horrible racist’ while on the EU referendum campaign trail n Derbyshire.

Asked about her comments, Mr Hunt told Sky News yesterday: ‘This is why we need a root and branch rethinking of this issue within the culture of our party, because if people think we’re only saying one thing in this studio but when I leave this studio I think something else, well they’re not going to trust us.

‘It is not racist to talk about immigration. It is not racist to reflect on the changes that happen to communities.’

Their intervention came as a new inquiry into Labour’s election woes warns that the party is becoming ‘toxic’ outside the M25 because of its failure to address immigration.

Jon Cruddas, who served as Ed Miliband’s policy chief, will warn this week that Labour is becoming ‘irrelevant to the majority of working people’.

In a new report on Labour’s election defeat last year, Mr Cruddas will warn that the party is at risk of losing more votes to Ukip unless it ‘stops patronising’ socially conservative supporters.

The report goes on: ‘Labour is becoming a toxic brand. It is perceived by voters as a party that supports an “open door” approach to immigration. Lacks credibility on the economy and is a “soft touch” on welfare spending.’
