This has emerged in our cottage garden during May. Flower stems are thick and upright, one is now over six feet tall. Flower heads are umbellate, similar to cow parsley and in bud about to flower, probably white or cream. Leaves are dark green, thick veined and similar in shape to rhubarb leaves but with more jagged edges.
Please can someone identify?

Hi Diana, we will share your images with our community. Please be careful. - it may be "Giant hogweed"

"Giant hogweed (Heracleum mantegazzianum) is a close relative of cow parsley originally from Southern Russia and Georgia. It can reach over 3m (10ft) in height. Although this striking plant can be attractive in certain situations, most gardeners will want to eradicate it, as it is potentially invasive and the sap can cause severe skin burns. It is widely distributed in the wild and poses a serious risk to people who are unaware of its potential for harm." Source RHS.

If it it IS, be careful. It can cause serious burns to humans and pets. We don't yet have this plant in our database but we are just a bit concerned for you that may be that plant.

Attached is an ID sheet (source: http://invasivespeciesireland.com/wp-content/uploads/2018/06/AE1-17-407392-17.18.055-Invasive-Species-ID-Sheets-Giant-Hogweed-final.pdf)

Cheers, Nicola

Another, more common garden plant suggestion from our followers, is "Crambe cordifolia"

Another vote for this plant being Crambe cordifolia but not 100% sure.

"Giant hogweed has much bigger, divided leaves and the flower head would be much more umbellate. Could be wrong though - let’s see what others say"

Another vote for "Crambe cordifolia, methinks, as featured on our garden pic of the day."

The Crambe cordifolia looks most promising so far. I had already checked for Giant Hogweed and I really don't think it is that. The leaves are the wrong shape and my flower stem is pure green, not streaked darker as is Giant Hogweed.
Can you advise on how to support the flower stems because they are so heavy they are falling over, even before the buds get to full flowering?
Thank you

Diana, another vote for Giant Hogweed from our followers.

"Looks like it (Giant Hogweed) to me! Don't touch it, all will be revealed when the flowers open."

It isn't giant hogweed, it isn't hairy and the leaves are wrong.
