David Lammy has, as it known in common parlance, ‘done a Lammy’:

When I was growing up my mum relied on tax credits. Tonight in opposing the Welfare Bill I voted for millions of people who do the same.

Now then.

Tax credits were introduced in 2003.

David Lammy was born in 1972.

That means Lammy was 31 when tax credits were introduced.

At least he didn’t say Marie Antoinette won the Nobel prize for her work on radiation. Oh.
