The Mayor of London's latest radio appearance saw him leave the door open to making a bid for Parliament at next year's General Election.
After long-awaited good news on the economy, an esteemed report paints a worrying picture of the huge problems the country still faces.
The Chancellor has said he is in favour of a rise in the minimum wage above the rate of inflation in an apparent turnaround.
The EU has now frozen the assets of 18 people suspected of "misappropriating" Ukrainian state funds - including ousted president Viktor Yanukovich.
Chancellor George Osborne announced the asset freeze would take place on Twitter:
We are freezing assets across the EU on 18 Ukrainians suspected of misappropriating Ukrainian state funds
The Chancellor's decision to rule out sharing currency with an independent Scotland will prove to be a "monumental error", First Minister Alex Salmond will declare.
Mr Salmond is expected to say in a lecture tonight: "In the last three weeks people in Scotland have seen an array of approaches from the UK Government - what they apparently call their 'Dambusters' strategy.
"We were love-bombed from a distance by David Cameron, then dive-bombed at close range by George Osborne.
"Scotland will not be a foreign country after independence, any more than Ireland, Northern Ireland, England or Wales could ever be foreign countries to Scotland".
George Osborne said the Government's latest clampdown on tax evasion`would make it very clear to people that if they do not pay their taxes then "we are coming after them".
The Chancellor said, "It is not fair for people to do that, it means that other people have to pay higher taxes and ultimately, as a society, we've all got to make a contribution."
Chancellor George Osborne has announced a new clampdown on tax evasion targeting offshore account holders.
He warned that anyone who fails to declare all of their income will have to pay the tax itself as well as penalties of up to twice that sum, and they could even face imprisonment.
Mr Osborne said: "We're throwing all the resources of the HMRC, our tax collectors, behind this. We'll be running adverts to give people fair warning that if they're hiding money offshore overseas that's not acceptable.
"We will find people - they have to pay their taxes and ultimately this is about fairness".
The new campaign will run in national newspapers and weekly magazines from tomorrow.
Speaking in Hong Kong earlier, Chancellor George Osborne has said that it would be a "huge mistake" to believe more tough decisions were not needed despite improvements in the economy.
The British economy cannot rely on just consumers and bankers for economic growth, the Chancellor has said.
Providing a small window into next mont's budget, George Osborne said he wanted to see a return to British manufacturing, in a speech to business leaders in Hong Kong:
– George Osborne
The recovery is not yet secure and our economy is still too unbalanced.
We cannot rely on consumers alone for our economic growth, as we did in previous decades.
And we cannot put all our chips on the success of the City of London, as my predecessors did. Britain is not investing enough. Britain is not exporting enough.
Gross domestic product grew by 0.8% in the third quarter of 2013 and by 0.7% in the final three months of the year, although Bank of England experts believe fourth quarter growth will be revised up to around 0.9%.
The Chancellor has given the strongest suggestion yet he will continue with cuts, despite the recent positive economic growth.
In a speech to business leaders in Hong Kong, George Osborne said he has no intention of deviating from his "plan A" for the economy and will be sticking to the austerity programme he began in 2010.
Mr Osborne said it would be a "huge mistake" to "abandon" the austerity programme and said the UK would continue to deal with both "our debt and our deficit".
His comments follow a sharp upgrade to UK growth forecasts from the Bank of England last week, which predicts growth of 3.4% this year, up from 2.8% previously.
Alex Salmond has said that the Chancellor is playing politics with the Scottish independence referendum.
The Scottish First Minister told ITV News: "Why should I be knocked off what's best for Scotland, best for the UK just because George Osborne is playing campaign politics? We say the day after the referendum he'll be singing a different tune."
George Osborne's stance on a currency union with Scotland has "backfired" according to First Minister Alex Salmond.
Speaking to business leaders today Mr Salmond said Mr Osborne's speech had been received "poorly" in Scotland.
He said: "Phone-ins, newspaper polls taken after the Chancellor's statement indicated his diktat had backfired badly.
"People do become sick and tired of the succession of day-tripping Conservative ministers flying up to Scotland to deliver lectures and then flying back to Westminster again."
