Now. Who would live in a house like this?

As a footballer, Sol Campbell was a rock in the England and Arsenal defence. In his retirement, he has become an outspoken critic of Labour's plans for a "mansion tax" on properties worth more than £2m.

Today, he went head-to-head on The Daily Politics with shadow Welsh Secretary Owen Smith. Mr Campbell said: "An Englishman's home is his castle but under Labour's proposal for a mansion tax that castle is under threat." He accused Labour of trying to "penalise those individuals who've done well for themselves". It was he said "anything but fair - and it's flawed".

Mr Campbell, who has been flirting with the Conservative Party, argued that he's spent millions of pounds in income tax and stamp duty and was being punished for investing in a property portfolio. The mansion tax, he said, was "a tax on aspiration".

Mr Smith chose attack as the best form of defence, telling him: "I think that people in this country who are, frankly, struggling under this government will have zero sympathy for millionaires like you pleading poverty. It's just not going to wash, Sol."

The money raised from the "mansion tax" would go to fund the NHS, which again dominated prime minister's questions in the House of Commons. St Albans Tory MP Anne Main - who is originally from Cardiff - told David Cameron:

"Sadly, my mother died under the Welsh health service and it was in the inquest revealed that ambulances routinely had kit that hadn't been checked and things had been left out of them. Do you share my concern that its taken the death of another person in Wales to get a change to this service?"

As usual, the prime minister didn't need an invitation to discuss the NHS in Wales: Prime Minister David Cameron said: "There's a debate on Wales in the House today, but not a debate about the health service in Wales which we should have a debate about, because in Wales they made the decision to cut the NHS budget - rather than to increase it as we've done in England, they haven't met an NHS target on cancer or waiting times since 2008. The NHS in Wales is in trouble, and that's not because of hard-working doctors and nurses, but because of a Labour administration that cut the NHS and has failed to reform it."

Labour leader Ed Miliband also chose to question Mr Cameron on the NHS - although no-one has yet accused him of waging a "war on England". Back in the Daily Politics studio, Owen Smith defended the Labour-run Welsh NHS, this time in debate with Tory chairman Grant Shapps.

Unlike in England, said Mr Smith, the Welsh health minister hadn't taken his children to A & E to avoid a long wait to see a GP. As Sol Campbell would acknowledge, the NHS remains a political football.
