Can anyone tell me what this is please?

[Weepingwillows12]

I had a weed take over my garden this year. Was hoping it would die back a bit in winter but doesnt seem to so need to properly tackle it. It's hard to pull up as just snaps rather than robots coming up.

Anyone know what it is and how to get rid?

That's Common Mallow. I think. It may flower in summer.

I agree it looks like Mallow, which is actually edible. Tastes like Spinach

Looks to me like Wood Avens (Geum urbanum), also known as Herb Bennet. Very pretty wild flower (in the right location!), but, yes, very invasive in a garden. If you want to avoid using herbicide I would suggest using a long thin bladed gardening trowel, a daisy grubber or invest in a Japanese 'Hori Hori' gardening knife to remove it, roots and all. Sorry to be the bearer of bad news, but there will also be a 'seedbank' in the soil and new seedlings will inevitably appear which you will also need to remove in due course - it will be a long, slow process I am afraid

I second herb bennet.
Absolute pain in our garden. Has rhizomes so can regenerate from little bits left in soil. Spreads very easily.
Only way I can control it in our beds is to diligently dig out each and every plant let while they’re small. Make sure you get the whole rosette.

The leaves are a completely different shape to herb bennet.

Pic above is Mallow. Here's one of Herb Bennet

[Weepingwillows12]

The leaves are about palm of your hand size. Does that fit with mallow?

[Weepingwillows12]

At least the largest ones are. There are smaller ones too. It's very annoying. Covers one bed now and pops up in every paving crack. Another bed is covered in celendine. Was watching this year gone to see what we have as is a new garden. What we have is weeds! Haha.

The leaves in the OP's photographs are those of young Herb Bennet without a doubt - where is @meredintofpandiculation when needed for a definative id?!

[BillHadersNewWife]

BEekeeper but they're completely different.

[grendel]

Young herb bennet leaves are rounded like in the ops picture. When they start to put on growth and send up stem on which the flowers form, the leaves get more pointy like in the later photos. (Have spent far too much time in close combat with the herb bennet in our garden!)

That having been said, op says that leaves are the size of a palm which seems quite big to me. Or maybe in grows bigger in more favourable conditions?

Key question for op is, did it flower last year, and if so what were the flowers like?

[Weepingwillows12]

I didnt notice a flower sorry. It became quite prolific around july onwards.

[MereDintofPandiculation]

My first impression was Water Avens (same genus (Geum) as wood avens/herb benet). If wood avens had been around for a season it would be showing the mature leaves. I'm not confident on Water avens either. Growth habit seems wrong - too big a uniform patch, no sign of clumping. But if the OP has been weeding it all season?

But if it looks like a Geum there's always a possibility it's a garden variety. My suggestion would be to leave it till it flowers, then fork it out if it's not wanted.

[MereDintofPandiculation]

Mallow isn't a bad suggestion (BillHadersNewWife your pic is a mature Geum urbanum leaf - the younger leaves are round, without the leaflets). On the other hand, I think the bottom RH leaf is showing an extra pair of leaflets on the stem, and if that is what I'm seeing, it would rule out mallow.

[Weepingwillows12]

I havent been weeding it. I had a little go and was just snapping off the leaves so was waiting to winter to remove, thinking it might be easier. Thanks for these suggestions. Giving me stuff to google.
