Delegates from the Unite have "overwhelmingly" voted to suspend Deputy Prime Minister Angela Rayner's membership for backing a "rogue council" amid the trade union re-examining its relationship with the Labour Party.

The decision comes after an emergency motion at Unite's policy conference in Brighton where it condemned Birmingham's Labour council and the Labour Government "for attack the bin workers".

"Unite has overwhelming voted to re-examine its relationship with Labour and deputy prime minister Angela Rayner has had her Unite membership suspended over her role in the Birmingham bin strike," a union statement said.

The union confirmed that Birmingham Council leader John Cotton along with his "fellow Unite" councillors had also had their memberships suspended.

"(It comes after) their roles in effectively firing and rehiring the workers," the statement continued.

"(They) are striking over pay cuts of up to £8,000."

Unite General Secretary Sharon Graham said the union was "crystal clear it will call out bad employers regardless of the colour of their rosette".

"Angela Rayner has had every opportunity to intervene and resolve this dispute but has instead backed a rogue council that has peddled lies and smeared its workers fighting huge pay cuts," Graham said.

“The disgraceful actions of the government and a so-called Labour council, is essentially fire and rehire and makes a joke of the Employment Relations Act promises."

Graham added that "people up and down the country" were asking which side the Labour Government was on and it was clear it wasn't the "workers".

The conference also condemned Birmingham Council "for its threat to effectively fire and rehire, on pain of redundancy, the Unite Birmingham bin workers".

The Labour Government was also under fire from the union, with the statement further declaring it had supported the "council and the commissioners (which were) originally appointed by the Tories and maintained by Labour".
