EU referendum in the Anglia region

Culture Secretary John Whittingdale has bet £1,000 that David Cameron will remain Prime Minister even if the British people go against his wishes in June's referendum and vote for Britain to exit the EU.

Mr Whittingdale, one of six ministers to declare for the Brexit campaign, denied his leader's position would be untenable if he was defeated on the issue.

He accepted the bet for charity with presenter Piers Morgan on ITV's Good Morning Britain:

• Boris Johnson backs 'once in a lifetime' Brexit campaign

Boris Johnson has suspended his battle bus campaign across the East, after Labour MP Jo Cox was shot in her West Yorkshire constituency.

Boris Johnson had been drumming up support in Norfolk and Suffolk for the campaign to leave the EU.

The former London Mayor was due to visit Ipswich this afternoon, after spending the day on the Vote Leave battle bus in Lowestoft, Cromer and Norwich.

The official campaign for Britain to remain in the EU has also suspended all activity for the day following the shooting.

Prime Minster David Cameron has arrived in Bury St Edmunds.

The PM was at the Greene King Brewery as part of his campaign to encourage voters to stay in the EU.

The Chancellor George Osborne has been in Essex claiming that leaving the EU would be a one way ticket to a poorer Britain.

He spoke alongside political opponents Labour's Ed Balls and Vince Cable from the Liberal Democrats as the Remain campaign staged an event at Stansted Airport.

They warned that Brexit could mean an end to cheap flights and threaten investment such as the new Ryanair training centre which will create 450 jobs.

The Vote Leave campaign pointed out that the Ryanair boss Michael O'Leary said only a few months ago that Brexit would not cause fares to rise.

The Stansted announcement comes after more than 300 business leaders urged Britain to vote to leave the European Union, warning that the country's competitiveness is being undermined by its membership.

In a letter to The Daily Telegraph, they argued that businesses will be "free to grow faster, expand into new markets and create more jobs" if they are unconstrained by EU rules.

It's the Prime Minister's second visit to Suffolk within a fortnight on the referendum campaign trail. He was in Ipswich at the end of February
