Prime Minister To Lay Out Plans For The East
David Cameron will highlight the Government's economic record in a speech in Felixstowe today, promising a ``brighter future for hard-working people'' ahead of a speech to business leaders.
The Prime Minister, who received a boost from the latest official figures showing falling unemployment and rising wages, said he was "determined to go further'' in creating more jobs.
Chancellor George Osborne said his plan for the East of England region will result in 250,000 more jobs by 2020.
Mr Cameron, who will deliver a speech in Felixstowe, highlighted the region's strengths in the science, defence and energy sectors.
He said: "Our long-term economic plan is working in the East of England. The region has 80,000 more businesses and the fastest growth in employment in England outside London.
"Nearly 200,000 more people have the financial security that a job and regular pay-packet bring since 2010.
"I am determined to go further and we will keep working through our plan to secure a brighter future for hard-working people across the East of England by making the most of the region's strengths in science, defence and energy, ensuring we have world-class infrastructure and backing business to create more jobs.''
Mr Osborne said: "The East of England is growing and creating jobs, and on many measures doing so more quickly than other parts of our country. We need to maintain this which is why the Prime Minister is today outlining the next steps in our long-term economic plan for the East of England. That plan will aim to create 250,000 new jobs and boost the East of England's growth by over #12 billion.''
The visit comes after official figures yesterday showed the UK's jobless total dipped by 97,000 in the quarter to last December to 1.86 million, almost half a million down on a year ago, while employment increased by 103,000 to almost 31 million, the highest since records began in 1971.
Pay continued to rise in real terms, with average earnings increasing by 2.1% in the year to December when CPI inflation was 0.5%.
