JEREMY CORBYN has criticised the government for blowing more than £9 million of taxpayers’ cash on pro-EU propaganda.

The Labour leader will make a major speech today setting out the party’s official position to remain in the EU.

But he said yesterday that ministers had a responsibility to take a “more even approach” before the June 23 referendum.

Mr Corbyn spoke out as the government faced a backlash over the glossy 14-page pro-EU booklet sent to 27 million homes in Britain this week at a cost of £9.3m.

Some have posted the leaflets back to Downing Street and even supporters of continued EU membership have warned that such a partisan approach could backfire.

It also sparked a row on the Tory benches at Prime Minister’s Questions yesterday.

Backbencher Jacob Rees-Mogg branded it a “propaganda sheet” that contained “untrue” information, prompting Mr Cameron to accuse him of spreading a “scare story.”

Afterwards, a Labour spokesman said: “Jeremy is of the view that they should have taken a more even approach to information to allow the public to make an informed decision, while we would still campaign to remain in Europe.”

Public-service union Unison announced yesterday that it will campaign to Remain in the EU after a consultation with branches.

It found that 78 per cent wanted Unison to take a stance and, of those, 98 per cent backed a Remain vote.

General secretary Dave Prentis said: “Europe isn’t perfect, but on balance staying in the EU has so much more to offer nurses, teaching assistants, town hall staff and other public servants than an uncertain future where the UK goes it alone.”

Vote Leave was designated the official Brexit campaign group by the Electoral Commission yesterday. Benefits of being the “official campaign group” include a higher spending limit of £7 million, one free leaflet to households and referendum campaign broadcasts.

The Trade Unionist and Socialist Coalition (TUSC), one of three EU exit organisations that applied for recognition from the Electoral Commission, accused the commission of “bowing to political pressure” in giving the Tory-dominated Vote Leave group official designation status.

But Vote Leave labour movement co-ordinator Ian Davidson said: “Vote Leave wants to ensure that progressive and left voices are heard in the debate, and wants to work with them for a Britain and Europe free from the EU.”
